Buying running shoes should be quite simple.
You need something comfortable, suited to where you run, that fits your feet and lets you get on with running.
Then you enter a running shop.
Neutral. Stability. Maximum cushioning. Low drop. High drop. Rocker. Carbon plate. Energy return. Motion control. Daily trainer. Tempo shoe.
Suddenly it feels as though you need a biomechanics degree before you're allowed near the till.
You don't.
There are genuine differences between running shoes, and some of those differences matter. The problem is that footwear science is far less tidy than running-shoe marketing sometimes makes it sound.
This guide will help you ask better questions, narrow down the choices and find a shoe that actually works for you.
The highlights
- Start with what you need the shoe to do, not which model everybody else is wearing.
- Fit and comfort matter more than finding the supposedly perfect category for your foot.
- Pronation is a normal part of movement. Seeing some pronation does not automatically mean you need a stability shoe.
- Cushioning, stability and heel-to-toe drop can change how a shoe feels and how you move, but there is no single specification proven to prevent injuries for every runner.
- Try several shoes and keep the one that feels naturally comfortable rather than the one you feel you ought to like.
Start with the job
Before looking at shoes, answer one question:
What am I actually buying these for?
A shoe for three relaxed road runs each week has a different job from something intended for muddy winter trails or a marathon PB attempt.
Think about:
- where you run
- how far you usually run
- whether this is an everyday shoe or something more specialised
- what you like and dislike about your current shoes
- whether you are currently pain-free
- your budget
If most of your running is on pavements, roads and firm park paths, a normal road-running shoe is the obvious starting point.
If you regularly run on mud, loose rock or steep trails, grip and protection start to matter more. We cover that separately in our road-versus-trail guide.
If you are new to running, you almost certainly do not need a wardrobe of different shoes for different sessions.
One comfortable pair of everyday running shoes is a perfectly good place to begin.
Fit comes before technology
The most sophisticated midsole in the world is not particularly helpful if your toes are being squashed into the front of the shoe.
Look at:
Length
Your longest toe needs clear space ahead of it. General podiatry guidance suggests around 1 cm as a useful starting point, although the shape of your toes and the shoe both matter.[1]
Width
Your forefoot should not feel squeezed simply because the shoe is technically the right size.
Depth
Some feet need more room above the toes or across the midfoot.
Heel fit
The heel should feel secure without the shoe digging into the Achilles area.
Overall comfort
Nothing should immediately rub, pinch, press or make you want to adjust the shoe.
Try both shoes. Feet are often slightly different sizes.
And wear the sort of socks you actually run in.
We have a complete guide to running-shoe fit if you want to go further.
Comfort is not a soft option
For years, footwear selection often focused on trying to classify somebody's foot and then assigning the appropriate category of shoe.
More recent research has questioned whether shoe prescription can really be reduced to such a simple formula.
A 2022 review examining the major theories behind running-shoe selection found limited evidence supporting any single injury-prevention paradigm. The authors suggested that, for many runners, comfortable and relatively lightweight footwear is a sensible starting point.[2]
More recent evidence adds something interesting.
A 2025 secondary analysis of a large randomised footwear trial found an association between higher overall shoe ratings and lower injury risk. Greater perceived cushioning was also associated with lower injury risk.[3]
There are important limits. Runners rated the shoes during the study, sometimes after an injury, so pain could have influenced their answers. The association with overall shoe ratings also disappeared when the researchers accounted for cushioning perceptions alongside them.
That does not prove:
comfortable shoe = injury-proof shoe.
It does suggest that how a shoe feels to the person actually wearing it deserves to be taken seriously.
When you try shoes on, notice whether you relax into them.
A good shoe often feels fairly unremarkable.
You should not need to convince yourself that the strange pressure under your arch will probably disappear once you've spent £150.
How much cushioning do you need?
There is no scientifically established number of millimetres of foam that every runner needs.
Some people love a soft, highly cushioned ride.
Others prefer something firmer and closer to the ground.
Cushioning can affect running mechanics, but softer does not automatically mean safer and firmer does not automatically mean faster.
One particularly useful randomised trial followed 848 recreational runners using otherwise similar shoes with either softer or harder cushioning.
The runners in the harder shoes experienced a higher injury risk overall.[4]
Interestingly, the protective association of the softer shoe appeared in the lighter group rather than the heavier group. That runs against the common assumption that heavier runners automatically need more cushioning.
The lesson is not that everybody should buy the softest trainer they can find.
It is that simple rules such as:
"You weigh X, therefore you need shoe Y"
are not well supported.
Compare different cushioning levels and pay attention to which feels comfortable and controlled.
Neutral or stability?
A neutral shoe generally contains fewer features specifically intended to influence inward foot motion.
A stability or motion-control shoe includes design features intended to provide greater support or influence how the foot moves.
The old rule was often:
You pronate, therefore you need stability shoes.
That is too simplistic.
Pronation is a normal movement. A study following 927 novice runners in neutral shoes found no higher overall injury risk in those with moderately pronated feet. There were too few highly pronated feet to draw a firm conclusion about that group.[5]
However, that does not mean support shoes are pointless.
A randomised trial involving 372 recreational runners found a lower overall injury risk in the group allocated motion-control shoes. A secondary analysis suggested that runners with pronated feet might have gained the greatest benefit. That subgroup finding was preliminary, and the trial tested one shoe design rather than every stability shoe on the market.[6]
So what should you actually do?
If you currently run comfortably in neutral shoes with no recurring problems, there is little reason to panic because somebody filmed your ankle rolling inward.
If you have repeatedly found supportive shoes more comfortable, or have a history of problems that might be relevant, trying a stability option is reasonable.
If you have persistent or recurrent pain, footwear selection should form part of a broader assessment rather than being treated as the diagnosis.

What does heel-to-toe drop mean?
The drop is the difference in height between your heel and forefoot inside the shoe.
For example, if the heel sits 30 mm above the ground and the forefoot 22 mm above it, the nominal drop is 8 mm.
Shoes can range from zero drop to more than 10 mm.
A randomised trial involving 553 runners compared shoes with 0 mm, 6 mm and 10 mm drops.
Overall injury risk did not significantly differ between the groups.[7]
There were different findings when researchers separated occasional and regular runners, which is another reason not to turn one drop number into a universal prescription.
Changing drop can alter how load is distributed through your legs and feet.
If you have happily run thousands of miles in a conventional higher-drop shoe, there is no prize for suddenly moving to zero drop because somebody on social media says it is more natural.
Treat a large change in shoe design as something your body may need time to adapt to.
What about super shoes and carbon plates?
Modern racing shoes combining lightweight responsive foams, increased midsole thickness and stiff plates can improve running economy.
Recent meta-analysis supports a real performance effect from advanced footwear technology.[8]
That is useful if you are chasing race performance.
It does not make carbon-plated shoes necessary for ordinary running.
A beginner preparing for her first 5K does not need a £250 racing shoe to become a legitimate runner.
For everyday training, comfort, durability, fit and suitability for the surface are usually more important.
Does lighter mean better?
For performance, shoe weight can matter.
Adding mass to footwear increases the energy required to run, and controlled experiments have demonstrated poorer running economy with heavier shoes.[9]
But weight should not be considered in isolation.
A shoe that is 30 grams lighter but rubs your heel, feels unstable or leaves your feet aching is not an upgrade.
For normal training, treat low weight as a nice characteristic once the important things are already right.
Do women need women's running shoes?
Women's feet are not simply miniature men's feet.
Research using three-dimensional measurements of women's feet has questioned the assumption that women's running shoes can be made simply by scaling down men's shoe lasts. A last is the mould around which a shoe is made, so its shape matters.[10]
However, this does not mean every shoe carrying a "women's" label will automatically fit you better.
Women have hugely varied feet.
Some need a narrow heel and broad forefoot.
Some need greater overall width.
Some have high-volume feet.
Some fit beautifully into a unisex shoe.
Choose the shoe that fits your actual foot rather than the demographic printed on the box.
Should you have gait analysis first?
You can.
You do not have to.
Video gait analysis can measure useful things, particularly features such as foot-strike pattern and step rate.
What it cannot do is scan you for thirty seconds and reveal one scientifically perfect running shoe.
We have written a separate guide explaining what gait analysis can tell you and where the claims sometimes get ahead of the evidence.
A sensible shop test
When you have narrowed the options:
- Try several different models rather than just one.
- Wear both shoes.
- Walk around.
- Jog in them if the retailer allows it.
- Try a couple of gentle changes of direction.
- Notice pressure, heel movement and toe space.
- Compare the shoes directly.
- Ignore the colour until you have narrowed down the comfortable options.
Then ask yourself:
Which pair did I stop thinking about?
That is often a more useful question than:
Which pair contains the cleverest technology?
When to get professional help
If you are pain-free and simply buying running shoes, you do not necessarily need a clinical biomechanical assessment.
If you have persistent pain, repeated injuries, significant foot problems, neurological symptoms or a medical condition affecting your feet, the situation is different.
A podiatrist, physiotherapist, sports doctor or other appropriately qualified professional can assess the wider picture.
Shoes are equipment.
They should not be asked to diagnose you.
The Running Woman verdict
There is no single best running shoe.
There is a best shortlist for what you want to do, followed by the shoe that fits and feels best on your feet.
Start with:
Where am I running?
Then:
Does it fit?
Then:
Is it comfortable?
After that, think about cushioning, support, drop, weight and all the clever technology.
Running shoes can be wonderfully complicated.
Choosing them doesn't have to be.
