It’s noteworthy to mention that you can choose whatever shoe you feel comfortable in, even if it belongs to the other gender. In this quick guide, we answer the questions “How Running Shoes Differ Between Men and Women?”, “Can Women Put on Men’s Running Shoes?” and “How to Convert the Women’s Running Shoe Size to Men’s Size? ”

How Running Shoes Differ Between Men and Women

A handful of catalysts make running shoes differ between the two genders. That’s why shoe brands design men’s and women’s shoes differently though they carry the same name. Since men and women are at variance biologically, they differ in running and landing on the ground. So, here is how men’s and women’s shoes differ from each other.

The Way the Shoe Looks

When you compare the shape of women’s shoes to that of men, you will find that the shoe’s design reflects the difference between masculine and feminine leg shapes. To explain, women’s shoes are bigger in the forefront and toes part and thinner in the heel area. Besides, men’s running shoes are generally larger and wider than women’s running shoes. Although many brands manufacture bigender shoes, such shoes feature differences in the midsole, outsole, upper, weight, and heel material.

The Q Angle

The Q Angle is the angle of the knee, which is known for being wider in women than in men because women have larger hips than men. As a result, the tendency of pronation among women is higher than that among men. Therefore, women need more supportive sneakers that help them reduce pronation and provide shock-absorbing features. Pronation can be divided into overpronation and underpronation. The first occurs when the effect of running shocks can’t be diffused, whereas the second happens when the outer part of the foot carries most of your body weight, which leads to wounds and falls. That’s what shoe manufacturers consider when it comes to producing different men’s and women’s outsoles and midsoles.

The Impact of Weight

Women have more lightweight muscles than men. According to biological studies, women’s muscle weight is less than men’s by about 15%. It explains why women’s shoes tend to show that difference by creating a lighter midsole. The flex grooves on the front of women’s shoes are also deeply immersed to put up with the low mass of women’s bodies.

Individual Suitability

After all, the shoe’s fit is based on what each person prefers and needs. That is why shoe brands always attempt to tailor a wide range of shoes to accommodate the different needs of people. Nevertheless, most women’s shoes are narrow, so if a woman needs a larger shoe, she might opt for a men’s shoe and vice versa. Studies by the American Society for Orthopedic Foot and Ankle Association reveal that women with flat feet usually buy men’s shoes. The disparities between the genders’ shoes don’t stop people from catering to their needs.

How to Convert Women’s Running Shoe Size to Men’s Size – Sizing Chart

Whether you shop for a pair of unisex running shoes online or you want to buy an opposite-sex shoe, you have to know that sizing between men and women is different. Therefore, you need to follow a conversion rule and sizing chart to ensure you have the best shoe fit and get maximum safety and protection.

There is a rate that all shoe experts use to convert a woman’s shoe to a man’s or vice versa. A good rule of thumb is to add a 1.5 size to maintain the right fit. For example, this rate will allow a woman whose shoe size is 8.5 to use size 7 when it comes to wearing a man’s shoe. Likewise, a man whose size is 7 will sport a woman’s size 8.5, and so on.

The US men’s running shoe sizes are marked from 0.5 measuring 7 ⅔ inches to 15.5 or 12 ⅔ inches, while for US women, it starts with a size 2, which also has the exact 7 ⅔ inches measurement, up to US women’s size 17.

Keep in mind that sizing systems in the US and Canada differ from shoe measurements in Europe. Use the Below table for easy shoe converting between the US and European men’s shoe size systems.

European Shoe Size Conversion

In Europe, many shoe sizing guidelines are used to designate the dimensions of shoes. For instance, add 31.5 to your US men’s size to convert it into a European shoe size. Men need to add a half-size (.5) to their current UK shoe size to convert US sizes to UK sizes. For instance, a US 4.5 corresponds to a UK size 4 shoe.

Again, this conversion rate is a mere suggestion. Unfortunately, the rule is not deemed reliable to work with all cases. So, collecting other information about the running shoes you want to buy is a good idea. To make your experience with running shoes satisfying, you need to know the brand that suits you, the best socks for you, and the insoles that will keep you comfy.

Can Women Wear Men’s Running Shoes?

Yes, of course, they can! Women can even opt for boyish styles. For instance, girls whose size is 6 feet can wear a boy’s shoe that measures 4.5 in size. Since women’s footwear sizes are generally smaller than men’s, women are recommended to wear kids’ trainers. On the other hand, men’s shoes are tailored to feature a wide in-shoe room since men usually have flat feet. Moreover, the body weight of men is generally heavier than women’s, which Influences the pressure and force they run with. Therefore, it may help women with wide feet who cannot fit properly in their running shoes.

Please notice that buying your next running shoes is important from stores that provide a return policy (30 days is the most common). So, if you don’t find the shoes’ size is not the best fit, you can return them and get your money.

Advice for Runners with Small Feet

One key factor to be aware of is the historic sizing of men’s sneakers, as men with narrower feet might have a difficult experience putting on a pair of running shoes labeled M for medium. This is because, in the past, people were not as tall and heavy as they are nowadays. That is why men used to wear medium sizes (C Width). Currently, medium sizes are parallel with D, not C. Consequently, men who have small feet are required to pick a shoe that’s smaller in size by a half degree.


The listed below are the most frequently asked questions with detailed answers.

What Makes a Shoe Suitable for Me?

Running shoes need to have extra space in them when you wear them and before you start your run. As the runner keeps running, his/her feet tend to swell and expand. So, if your trainers have additional room, they should be snug to hold your feet tightly when running. If your running shoes fit you snugly before you start running, you’ll probably suffer from serious issues when your feet start to swell.

It is essential to give a little bit of space for your feet to expand (especially in the toe box) while you run and protect against any chaffing along the edges of the sneaker. So, a man who has found the ideal running shoes in a women’s style may convert his size 7 shoe to a 9 for more room. According to the equation above, a man with a size 8 foot will put on a 9.5, but the 9.5 might feel too restricting.

Do Insoles and the Laces Affect Running Shoe Fitting?

Some runners have to put on a special insole as their feet hurt, or one leg is much shorter than the other. Podiatrists and running experts usually recommend those special insoles. The lacing system usually consumes some space while they move the tongue back, and the larger the tongue, the larger this room will be. It is recommended to avoid constrictive sneakers and not to suffer from heel blisters.

What Happens When I Wear an Improper Shoe?

You can wear a shoe that belongs to the other gender as long as you have a comfortable in-shoe experience. The conversion rule will aid you if you wish to get a shoe from the other gender that fits you properly. Also, remember that female shoes are generally narrow to meet the market guidelines for women. On the other hand, men with small shoes will find women’s shoes very helpful to cater to their particular needs.

Does Sizing Change according to the Market’s Varied Brands?

Yes, it generally does. However, brands differ when it comes to their standardized sizes. Therefore, experts exhort buyers to get an idea about the different footwear models they want. Moreover, ensure that the conversion you opted for is to your benefit. For example, the Brannock device is used in shoe stores to get the actual feet size to help hesitant buyers make up their minds. Also, note that the size of your feet changes while you run; your feet might expand or shrink while you are running on the terrain.


Finding the best protective and supportive running shoe that meets the criteria of the proper fitting is essential and has a lot of benefits. It helps both men and women enjoy the quality of running, improve their performance, and boost their healthy lives.

When shopping for new running sneakers, you don’t have to be restricted by a limited collection. However, if your favorite color or style only is available in the opposite gender’s sizing, don’t lose hope. You can wear women’s or men’s sneakers by purchasing a size and a half smaller or bigger than you often wear. For men’s to women’s shoe size conversion, or vice versa, check with the standard converter mentioned above, and you will end up wearing the kicks you decide on in no time.
