Football boots are often chosen for comfort, performance and style. But for female players, the right boot could also play an important role in reducing injury risk.
For many footballers, choosing a new pair of boots comes down to three things: how they feel, how they look and whether they help them perform.
But what if there was another question players should be asking?
Are they actually designed for you?
For Dr Karli Richards, a podiatrist and researcher specialising in lower-limb injury prevention in female footballers, that question is becoming increasingly important.
Football boots have historically been designed around male anatomy, despite women having different foot shapes and biomechanical characteristics.
Research into female-specific boots is now growing, with scientists increasingly examining how boot design, traction and the interaction between the foot and playing surface could affect injury risk.
And according to Richards, it starts with something as simple as the shape of the boot.
Why Female Players Need More Than Smaller Men’s Boots
One of the biggest misconceptions around football equipment is that women's products simply need to be scaled down.
But female anatomy is different.
"We're not small men," Richards explains.
Women typically have a wider forefoot and narrower heel than men, while differences in lower-limb anatomy can also influence how the foot interacts with the ground.
For Richards, that means the ideal football boot should reflect those differences.
A female-specific boot should have a wider toe box to accommodate the forefoot, while the heel should be narrower to reduce unwanted movement inside the boot.
The arch is another important consideration.
Richards believes additional arch support can help accommodate female biomechanics and potentially reduce strain around the knee.
It is a reminder that a football boot is doing much more than simply protecting the foot.
Every part of it can influence how the body above it moves.
Why the Sole Plate and Stud Placement Matter
Perhaps the most surprising part of Richards' research is the importance of the sole plate and the studs underneath the boot.
Stud placement might seem like a minor design detail.
It isn't.
Certain areas of the foot, including the first and fifth metatarsal regions, need to be considered when deciding where studs are positioned.
And then there is the first metatarsophalangeal joint — essentially the big toe joint.
This is where Richards' explanation becomes particularly fascinating.
The joint needs to bend naturally when a player moves.
If the sole of the boot is too rigid underneath it, that movement can become restricted.
During our conversation, Richards demonstrated the relationship by asking me to raise my heel and then place it back on the floor.
The result was immediate.
When the heel stayed planted, the knee extended. When the heel lifted, the knee bent.
It sounds incredibly simple.
But that movement could have important implications for injury risk.
"If you can't bend your toes, it's hard to lift your heel up," Richards explains.
"And if your heel stays planted, your knee extends."
Allowing more movement through the forefoot therefore allows the heel to lift, which in turn allows the knee to bend more naturally.
Richards believes that could reduce stress on the ACL.
It is a perfect example of why football boot design cannot be looked at in isolation.
A decision made underneath the foot can influence what happens several joints higher up the body.
How Stud Length Can Affect Injury Risk
Then comes the question that every footballer and every parent buying boots for a young player should understand: How long should your studs actually be?
Richards' answer is surprisingly straightforward.
Shorter, more conical studs are generally preferable when the aim is to allow the foot some freedom to move, particularly on artificial surfaces.
The reason is simple.
If a stud digs too deeply into the ground, the foot can become fixed to the surface.
The player then turns, but the foot does not move with them.
That creates a situation where the lower leg and knee can continue rotating while the foot remains planted.
For a player attempting a sharp change of direction, that is the kind of interaction researchers are interested in when examining ACL injury mechanisms.
Excessive shoe-surface traction and "foot fixation" have been identified as potential contributors to lower-limb injury risk.
"You really want a shorter, more conical stud," Richards says.
"You want your foot to move a little bit."
That final point is perhaps the biggest takeaway.
A little bit of movement isn't necessarily a bad thing.
Why Too Much Traction Can Also Increase Injury Risk
Footballers understandably want traction.
Nobody wants to be slipping all over the pitch during a match.
But Richards says there is a balance between having enough grip to perform and having so much traction that the foot becomes stuck.
That balance becomes particularly important depending on the playing surface.
On a muddy pitch, more traction may be beneficial because the player needs additional grip.
On artificial grass, however, the equation changes.
Richards recommends being much more cautious about highly aggressive studs on artificial surfaces because of the increased possibility of the foot becoming fixed.
This is an area where the shape of the stud matters.
Short, conical studs generally allow more movement, while longer, bladed studs can provide greater traction.
Research comparing female-specific and male football boots has also found differences in traction depending on movement direction and surface, highlighting why stud configuration needs to be considered alongside the environment in which the boot is being used.
"There is a fine line between too much traction and not enough," Richards says.
And that line can change depending on the pitch.

Choosing the Right Football Boots for Different Surfaces
That creates another problem for players at grassroots level.
Most professionals have access to multiple pairs of boots.
For many young players, that simply isn't realistic.
Boots are expensive, and asking a parent to buy different pairs for every possible surface is not always an option.
Richards therefore recommends multi-ground boots for players who regularly move between surfaces and can only afford one pair.
The important thing is understanding what the boot is designed for.
If a player is regularly moving between natural grass and artificial grass, knowing the difference between firm-ground, artificial-ground and multi-ground studs can help them make a more informed choice.
And Richards believes parents should start paying particular attention to this as girls enter their teenage years.
"I think 12 to 14," she says when asked when parents should become more conscious of boot choice.
That is not to say younger players should ignore their footwear.
Rather, as players enter higher levels of competition and their physical development changes, understanding the interaction between their body, boot and playing surface becomes increasingly important.
Why Football Boots Are Only One Part of Injury Prevention
It would be easy to read all of this and conclude that choosing the right boot will prevent ACL injuries.
But Richards is clear that it isn't that simple.
Injury risk is influenced by numerous factors, including strength and conditioning, fatigue, recovery, playing surface and movement technique.
Her own preliminary research found that players wearing women's football boots were less likely to report lower-extremity injuries than those wearing men's football boots.
However, the survey involved around 100 players, meaning the findings are preliminary rather than definitive.
Richards also found lower reported injury rates among players who tracked their menstrual cycles and those who participated in strength and conditioning programmes such as FIFA 11+.
Those findings are part of a much bigger picture.
Her ongoing research is now examining additional factors including rest and recovery, playing surface and stud length.
The wider scientific picture is also evolving rapidly. A systematic review published in 2026 highlighted the complex relationship between boot design, traction, sole-plate stiffness, playing surface and lower-limb injury risk, while other recent studies continue to examine how stud shape interacts with sex and fatigue.
What Research Says About Female-Specific Football Boots
There is another reason Richards is particularly excited about the future of football boot research.
She is currently involved in a larger project comparing several football boots designed specifically around female anatomy.
The aim is to understand what is actually working.
That distinction matters.
The football industry has increasingly introduced boots marketed specifically towards women, but there is still a need for independent research examining whether those designs produce meaningful biomechanical differences.
A 2026 study involving researchers at the University of Essex and Brunel University London is similarly examining whether sex-specific football boots change the way female players move when running, jumping and changing direction.
For Richards, that research could help move the conversation beyond simply putting the word "women's" on a boot.
Because female-specific design should mean more than colourways and marketing.
It should mean understanding the athlete wearing it.
Why Players and Parents Need Better Football Boot Education
Ultimately, Richards isn't suggesting that there is one magic football boot that will eliminate injury risk.
Instead, she wants players, parents and coaches to understand what they are actually putting on their feet.
That means knowing the surface.
Knowing the studs.
Understanding how much traction is appropriate.
And recognising that the shape and construction of a boot can affect the rest of the body.
At professional level, players may have to make difficult decisions between performance and injury risk.
Richards gave the example of United States international Tierna Davidson, a player she works with who has previously suffered two ACL tears.
Ahead of a match on a muddy pitch, Davidson had to decide whether to wear her regular boots or screw-in studs.
The latter could provide the additional traction needed in difficult conditions, but also potentially increase the mechanical demands on the body.
There was no perfect answer.
At the highest level, performance matters.
But for young and grassroots players, Richards' advice is much simpler.
"Air on the side of caution."
And perhaps that is the biggest lesson from our conversation.
The football boot should never be treated as an afterthought.
It is the first point of contact between the player and the pitch.
And if we want to understand why female footballers suffer certain injuries at such high rates, perhaps we need to start by looking down.
