We’ve all seen the marketing. The on-trend ads, the influencer reviews, the bold claims: the newest elite racing shoes are softer, thicker, and more cushioned than ever before. The implied message is clear: softer equals more comfortable, and more comfortable equals faster.
But as runners, we know that what looks good in a 30-second video doesn’t always translate to the track.
If you’ve been tempted by the hype around these expensive super soft running shoes, you might want to read this before you hand over your credit card.
Let’s dive into why this trending design might actually be working against your running goals.
Quick Look.
Thinking about buying super soft running shoes for your next race or as your daily trainer?
Before you hand over your credit card, let’s cut through the marketing hype. I want to share with you my recent experience with a pair of super soft elite racing shoes and why the latest ultra-plush, cloud-like midsole foams might actually be working against your stability, energy return, and race-day performance.
Quick Answers for Runners:
- Are super soft running shoes actually faster? Not necessarily. While they feel plush in the store, ultra-soft foam often compresses too deeply on the road. This creates an unstable wobble that drains your energy and can actually mute the snappy rebound of the carbon plate.
- Do they protect my joints better? It’s largely a marketing myth. Because the foam often lacks a firm base, your stabilising muscles and ankles have to work overtime just to keep you balanced. Over long distances, this extra muscular effort leads to premature fatigue and can actually increase joint strain.
- How can I test a shoe for stability in the store? Try the Thumb Press Test (the foam should resist slightly and snap back quickly, not sink and slowly rebound) and the Single-Leg Balance Test (stand on one leg with your eyes closed—if you wobble, the shoe lacks the stability you need for race day).

My Real-World Test: Why I Returned My Elite Racers.
Recently, I learned the too soft lesson the hard way. I purchased a pair of Saucony Endorphin Elite 2s online (they were discounted so seemed a bargain), intending for them to be my weapon of choice for this year’s racing season, including the Melbourne Marathon. I was expecting magic.
Instead, after a couple of short test runs, I quickly realised these shoes were not going to work as my racing shoes for this year.
The midsole foam was ultra soft. In fact, it was too soft. With every footstrike, the foam compressed so deeply that the shoe felt considerably unstable. I experienced a distinct wobble underfoot.
Instead of the snappy, bouncy rebound and spring-forward propulsion I expected from an elite carbon-plated racer, the softness felt like it was absorbing some of the energy of my stride.
Even though the carbon plate was likely doing its job, its effect felt muted, buried between two thick stacks of squishy foam. In the end, I made the tough but necessary decision to return them. They simply did not give me the confidence or the bounce-forward step-through I wanted for race day.
This was a genuine surprise, especially considering my past success with other shoes in the Endorphin series, particularly the Endorphin Pro. However, as I started looking at elite racing shoes from other major brands, a clear pattern emerged: this pursuit of extreme, ultra-soft foam isn’t an isolated incident, but a widespread trend across the entire industry.
Read on to discover the shoe I switched to instead. It’s been an absolute revelation, delivering the exact performance boost, stability, and confidence I need to protect my feet over 42.2km…and the brand might just surprise you.
The Marketing Hype vs. Real-World Running Reality.
Why do brands keep pushing the boundaries of softness? Because it sells.
When you step into a running store and press your thumb into a plush, cloud-like midsole, your brain immediately registers comfort.
For the two minutes you spend standing on the carpeted floor of the shop, that shoe feels absolutely luxurious. Even walking around the store, they feel supremely comfortable and bouncy.
But running is not a static activity. Real-world running is dynamic, repetitive, and often takes place on uneven surfaces. A foam that feels heavenly during a brief store try-on can become a liability with repeated impact, especially over longer distances.
When a midsole is excessively soft, it lacks the structural integrity to handle the high-impact, high-frequency forces of actual running.
What feels like a ‘cloud’ in the store quickly turns into a sinking, unstable swamp on the road. Your running shoes should protect your natural gait and biomechanics, not compromise them. If a shoe forces you to change the way you run just to stay balanced, you will inevitably pay the price with early fatigue, unexpected soreness, and a massive drain on your race-day performance.
TIP: Decode the Marketing. When brands advertise plush, cloud-like protection for your joints, they are selling a feeling, not a bio-mechanical fact. The mistaken belief is that soft foam absorbs all the impact, sparing your tendons. In reality, without a stable base, that soft foam forces your ankles and calves to constantly micro-adjust. Over long distances, that constant stabilising effort is exactly what leads to tendon fatigue and joint soreness.
The Hidden Instability of Super Soft Running Shoes.
When a midsole is excessively soft, it doesn’t just compress vertically; it compresses laterally. This creates a phenomenon often referred to in the running community as ankle wobble.
Instead of the shoe providing a stable platform, your foot and lower leg muscles have to work overtime just to stabilise your body on that squishy foundation. This constant micro-adjusting alters your natural running gait and form.
Over thousands of foot-strikes, this increased instability and higher loading rate can elevate the risk of overuse injuries.
Research has linked this type of unstable, highly cushioned footwear to altered foot mechanics, increased ankle instability, and a rising rate of specific bone stress injuries, such as navicular stress fractures.
A running shoe should enhance your physiology, not force your stabilising muscles to fight for control.
TIP: A Crucial Note for Heavier Runners. If you carry more body weight, you need to be especially vigilant about ultra-soft midsoles. Physics dictates that a higher body mass generates greater ground reaction forces on footstrike. This means you will compress that squishy foam much deeper and faster than a lighter runner, severely amplifying the instability and ankle wobble effect. For heavier runners, a firmer, resilient platform isn’t just a performance preference, it’s a crucial safety requirement to protect your joints and maintain a stable, efficient gait.
How Excessive Softness Mutes Carbon Plate Energy Return.
We also need to talk about the carbon plate found in many performance or race shoes. A carbon fibre plate works by acting as a lever and a spring, but it requires a resilient medium to transfer that energy efficiently.
Think of it like jumping on a trampoline versus jumping into a mattress. If the foam is too soft, it can act like a shock absorber rather than a springboard. It dampens the initial impact, yes, but it also muffles the energy return.
The risk is that the foam absorbs the force that the carbon plate is trying to redirect forward. This is the sensation I was feeling with my new racers, they felt somewhat muted on the rebound; the plate’s potential felt buried by the ultra-soft foam surrounding it.
This was a first for me with the Endorphin line. Previously, I had always been highly impressed by the distinct spring-forward feel of the Endorphin Pro models. I believe the firmer foam in those models provides the more stable foundation needed to properly translate the carbon plate’s energy return, whereas this ultra-soft foam seemed to somewhat swallow it.
To combat this, some manufacturers use a dual-foam midsole construction: a softer foam in the top layer for plush comfort, paired with a firmer, more resilient foam beneath the plate to maintain stability.
Manufacturers spend enormous sums developing their mid-sole forms and some of these offer truly incredible performance, but I believe soft to the point of wobble and energy drain is simply too soft.
TIP: The Buddy Check for Shoe Stability. Don’t just rely on how a shoe feels when you’re trying them on instore. Bring a friend along and have them watch you from behind as you walk (or do a light jog). Ask them to look closely at the heel area: is the foam compressing excessively? Is there a visible wobble or roll to the outside or inside of your foot? Remember, the downward forces generated when running are 2 to 3 times your body weight. The compression and instability you see while walking will be dramatically exaggerated at running pace. If it wobbles in the store, it will wobble on the road.
The Pivot: Why Firmer Midsoles Deliver Better Performance.
After returning the ultra-soft racers, I went looking for a shoe that would actually deliver on the promise of high performance, stability, comfort, and explosive energy return.
I’ve had many shoes in my rotation over the years, and tested many brands and models. In my current rotation I have the aforementioned Saucony Endorphin Pro’s (4/5), Altra Escalante (3/5), Saucony Kinvara (3.5/5), Puma Nitro Elite (4/5), Li-Ning Challenger 5 (4.5/5). And have tested many other brands in the past, including Nike, Brooks, On, and Hoka, amongst others.
However, for this years racers, I turned to a shoe I knew and trusted, purchasing a fresh pair of the Li-Ning Feidian Challenger 5 for this year’s racing season (my previous pair has many reliable, high-performance kilometres on them).
The difference was night and day. The Feidian Challenger 5 offers a midsole that is less spongey, yet remains supremely comfortable. Because the platform is stable, my foot isn’t fighting to find its balance on footstrike. This resilient base allows the shoe’s geometry and plate to work exactly as intended, exhibiting a much more pronounced energy return and a distinct spring-forward feel with every single step.
With a confidence-inspiring structure, exceptional long-distance comfort, and truly impressive performance, this is the exact kind of resilient midsole platform needed to deliver the real performance edge of a racing shoe.

TIP: Context is Everything (Recovery vs. Race Day). Are highly cushioned, soft shoes bad for everyone? Not at all! If you are dealing with a flare-up of plantar fasciitis, or you are heading out for a very slow, easy recovery jog, or even a walk, where impact reduction is your only goal, a plush, max-cushion shoe can be incredibly therapeutic. The danger arises when manufacturers put that exact same ultra-soft foam inside an elite, carbon-plated racing shoe. A slow recovery shoe doesn’t need to be snappy or hyper-stable, but a marathon racing shoe absolutely does. Always match the shoe to the specific job!
3 Simple Tests to Check Running Shoe Stability Before You Buy.
Sometimes it pays to not only be aware of, but a little sceptical of the marketing spin of some of these brands. Here are three simple ways you can test a shoe instore to ensure it’s not a super soft trap.
- The Thumb Press Test: Press your thumb firmly into the midsole foam. If it sinks in too easily or slowly bounces back, it’s likely too soft for stable, high-speed running. You want a foam that resists slightly and snaps back quickly.
- The Single-Leg Balance Test: Put the shoe on and stand on one leg. Close your eyes. Do you feel your ankle micro-adjusting or wobbling to keep you upright? If so, the shoe lacks the stability you need for long runs or race day.
- The Short Run Test: When you buy an expensive elite shoe, test them with a 3 to 5-kilometre run at your goal race pace. Pay close attention to how the shoe feels during and at the end of the run. Does it still feel springy and stable, or does it feel dead and wobbly? If so, return it.
Elite running shoes are a significant financial investment, which makes it tempting to convince yourself to just break them in if they feel a bit off. Don't do it. Marketing spin cannot override biomechanical reality. If a $300+ shoe fails these simple stability tests or feels wobbly on a short run, it will not magically fix itself by kilometre 35 of a marathon. You have the right to return them. Protect your feet, your form, and your wallet by trusting your own data over a glossy ad campaign.
Tip: The Hidden Danger of Extreme Stack Height. It’s not just about how soft the foam is, but how high it is. Many modern running shoes feature extreme stack heights (the total thickness of the midsole). While this looks impressive, raising your foot that far off the ground significantly elevates your centre of gravity. This doesn't just dull or eliminate your essential road feel, it acts like a lever, amplifying any lateral wobble and dramatically increasing the risk of rolling or spraining an ankle, especially on uneven surfaces or cambered roads. More foam does not always equal more safety.
Listen to Your Feet: The Ultimate Rule for Choosing Running Shoes.
The running shoe market is more exciting than ever, but it’s also full of hype. Some brands are pumping out truly impressive midsole foam tech, others are simply trying to appeal to the softer is better narrative.
The best shoe in the world is entirely subjective, and different for everyone. It’s the shoe that makes your body feel confident, stable, and ready to perform.
Don’t be afraid to return a shoe that doesn’t feel right, no matter how many five-star reviews it has, how many YouTuber's say it's the best shoe of the year, or how much the marketing promises. Your body’s feedback is the most important data point you have.

FAQ's: Super Soft Running Shoes.
What exactly are super soft running shoes?
Super soft running shoes are a recent industry trend featuring ultra-plush, highly compressible foams in the midsole. Brands market them as cloud-like for maximum comfort, but this extreme softness often comes at the direct cost of stability, road feel, and energy return.
Are super soft running shoes actually good for marathon racing?
Generally no. While they feel comfortable initially, super soft running shoes often lack the structural stability needed for 42.2 kilometres. The ultra-plush foam can cause ankle wobble and fatigue your stabilising muscles over long distances, while actually muting the energy return of the carbon plate.
Can super soft running shoes cause injuries?
Yes, they can increase injury risk. Because the foam compresses so deeply, your ankles and lower legs have to work overtime to stabilise your stride. Research links this type of unstable, highly cushioned footwear to altered foot mechanics, increased ankle instability, and a rising rate of mid-foot bone stress injuries.
Do super soft running shoes provide more energy return?
Actually, it can often be the opposite. For a carbon-plated shoe to deliver a snappy, spring-forward rebound, the foam needs to be resilient and provide a base of some resistance for the plate to work. If the foam is too soft, it acts like a shock absorber or a mattress, swallowing the energy that the carbon plate is trying to redirect forward.
What is the ankle wobble effect in running shoes?
Ankle wobble occurs when a shoe's midsole is so soft that your foot sinks and rolls slightly inward or outward on foot-strike. This forces your lower leg muscles to constantly micro-adjust to keep you upright, leading to premature fatigue, soreness, and compromised running form.
Why do people say you need a super-soft shoe to protect your joints, and is this true?
This is largely a marketing myth. While ultra-soft foam can offer short-term relief for specific issues like plantar fasciitis, it is mostly false for regular training and racing. Highly compressible foam lacks structural stability, forcing your stabilising muscles and joints to work overtime to keep you balanced. This premature fatigue actually increases joint strain over long distances. True protection comes from a stable, resilient platform that supports your natural gait, not a sinking foam.
What should I look for in an elite racing shoe instead of maximum softness?
Look for a shoe that offers a balance of comfort over long-distances and structural integrity. You want a midsole that is firm enough to provide a stable platform for the carbon plate to work, allowing for a pronounced energy return and a distinct spring-forward feel, rather than a sinking, mushy sensation.
