The design of trainers For each type, there are specific anatomical realities that directly influence foot comfort and support.
The differences between men's and women's feet are primarily anatomical. Studies show that women generally have larger feet. Narrow with a higher instep. This characteristic requires a suitable upper that harmoniously conforms to the shape of the foot.
Conversely, men often have larger feet large and relatively more dishes. According to podiatry research, the average difference in width between male and female feet varies between 3 and 6 millimeters for the same length. This variation may seem minimal, but it proves crucial for everyday comfort.
Bone structure and muscle distribution also differ, with bone density generally higher in men. These anatomical differences justify the adaptations made by manufacturers.
The manufacturers of trainers take these morphological variations into account in their design process. Thus, for the same shoe size, women's models present a narrower fit and one better defined arch of the foot.
Major brandsomme NikeOrAdidashave developed specific forms for each type. These distinct molds, called shapes Or lasts In English, they determine the internal dimensions and structure of the shoe.
Other brands, such as Converse Or Vans, They offer technically unisex models with an adaptable sizing system. This approach works particularly well for minimalist silhouettes that require fewer specific body-specific adjustments.
Size conversion is often a challenge when purchasing trainers of the opposite kind. Here's how to navigate between these different systems.
Three main sizing systems coexist in the global market for trainers :
The system European (EU) uses a simple numerical scale, identical for men and women. A size 40 EU corresponds to the same foot length, regardless of gender.
The system American (US) maintains a constant gap between men's and women's sizes. The general rule: a women's shoe size is equivalent to a men's shoe size plus 1.5 points. Thus, a men's US size 8 corresponds approximately to a women's US size 9.5.
The system British (UK) There is approximately a 1-point difference between men's and women's sizes. A men's UK size 7 is generally equivalent to a women's UK size 8.
This diversity explains why one must be vigilant when making international purchases of trainers.
Here are the main equivalencies between shoe sizing systems to facilitate your purchases:
Men's sizes (EU/US/UK) : 40/7/6 - 41/8/7 - 42/9/8 - 43/10/9 - 44/10.5/9.5 - 45/11/10
Women's sizes (EU/US/UK) : 36/5.5/3.5 - 37/6.5/4.5 - 38/7.5/5.5 - 39/8.5/6.5 - 40/9/7 - 41/9.5/7.5
To find the perfect size when buying online, measure your foot at the end of the day (when it's slightly larger) and consult the brand's size guide. Foot width is also a crucial factor, especially for women choosing men's styles.
The practical rule to remember: in the American system, add 1.5 points to your men's size to get the women's equivalent. Conversely, subtract 1.5 points from your women's size to find the men's equivalent.
Beyond the purely technical aspects, the trainers They are distinguished by marked aesthetic choices according to the targeted genre.
Women's models traditionally offer a a more varied color palette, including pastel shades, metallics, or vibrant colors. The finishes often feature details brilliant, , iridescent or accents metallic which add a distinctive touch.
THE trainers Men generally favor more vibrant colors neutral Or dark Black, white, grey, navy blue or khaki dominate the collections. Colour accents remain more discreet, generally limited to logos or sole details.
Regarding materials, women's designs more frequently incorporate soft textiles, of fine suede or elements satin. THE trainers Men favor more materials robust such as thick leather, technical mesh or resistant canvases.
THE trainers Women generally have a more defined silhouette fine And Slender, with a proportionally less imposing sole. The upper line follows the natural curves of the female foot more closely, creating a more fitted profile.
The male models display a more massive And geometric, with thicker soles and a wider structure. This visual robustness reflects the masculine morphology while corresponding to the associated aesthetic codes.
These differences are even found in iconic models. Nike Air Force 1 The female version has a slightly slimmer silhouette compared to its male counterpart. Adidas Stan SmithThe women's versions feature softer, cleaner lines than the men's version.
Faced with the limitations of gendered models, the industry is developing more and more unisex alternatives that meet contemporary expectations.
The market for trainers Unisex clothing has seen steady growth for several years. According to industry data, sales of gender-neutral models have increased by 18% between 2020 and 2022, reflecting a broader societal evolution.
Brands like Veja, , Common Projects Or Vans have made unisex design a central element of their identity. These companies offer collections based on universal shapes that adapt to all body types, regardless of gender.
This inclusive approach meets the expectations of a generation that questions traditional divisions. Minimalist models such as Converse Chuck Taylor or the Vans Old Skool are among the pioneers of this trend.
To select trainers unisex styles that perfectly suit your body shape:
Measure your feet precisely and consult the size guides specific to each brand, which often indicate the equivalencies between men's and women's sizes.
Women with wider feet will generally find more comfort in unisex sizes, while men with narrow feet may opt for slightly smaller sizes.
Adjust the lacing according to the width of your foot: classic cross lacing offers more flexibility to adapt the support according to your morphology.
Models like the New Balance 990, THEAdidas GazelleOr the Puma Sweden work particularly well in unisex versions thanks to their adaptable shape and balanced proportions.
In some cases, opting for a model of the opposite type may offer better comfort and fit.
For women with wider feet, choose trainers This can solve comfort issues for men. The conversion involves subtracting 1.5 sizes from their usual US shoe size. This option offers more room in the forefoot and is suitable for more robust foot shapes.
Men with narrow feet can benefit from women's shoe sizes that offer a more fitted look. Add 1.5 sizes to your standard shoe size to find the women's equivalent. This solution is particularly suitable for slimmer figures.
This practice is common for certain rare or exclusive models. Many women buy Jordan 1 or more Dunk in a men's version to access colours not available in the women's ranges.
Several traps await the buyer of trainers :
Do not rely solely on your usual shoe size without considering the specific sizing of each brand. Sizes can vary significantly between Nike, , Adidas Or New Balance.
Choose trainers solely for their appearance without considering their suitability to your body shape, which can lead to discomfort and foot problems.
Ignoring foot width, a factor as important as length for everyday comfort.
Buying online without precisely measuring your foot or without consulting reviews on the actual fit of the desired model.
Some manufacturers stand out for their specific approaches to gender differences.
Nike offers distinct collections with technologies adapted to each gender. The brand develops specific shapes such as the line Air Jordan A woman who is not simply a reduction of male models but a true redesign.
Adidas It adapts its flagship technologies, such as Boost and Primeknit, to the specific morphological needs of women and men. The women's UltraBoost offers a different level of support than the men's model.
New Balance is recognized for its multiple width system (B, D, E, EE) which allows for a more refined choice based on morphology rather than gender alone.
These differentiated approaches guarantee optimal adjustment and performance adapted to the biomechanical specificities of each gender.
Converse made unisex design its signature with the Chuck Taylor, a century-old model that transcends genders through its simplicity and adaptability.
Vans They primarily offer unisex silhouettes with an inclusive size chart. Their Old Skool and Authentic models are designed to fit all foot types.
Common Projects built its success on trainers minimalists without distinction of gender, prioritizing the quality of materials and the purity of lines.
This approach responds to a growing demand for inclusive products that prioritize style and comfort without imposing restrictive categorization.
