Key Takeaways
Traditional shoe sizing creates barriers that shouldn't exist. Wrong fit drives 53% of fashion returns, costing companies billions each year. Here's what matters when shopping for gender-neutral footwear:
Traditional sizing lacks foundation: The 1.5-size gap between men's and women's shoes has no scientific backing and fails 76% of women whose forefeet are wider than sizing charts expect.
Unisex sizing uses men's measurements: Women shopping unisex styles need to go down 1.5-2 sizes from their normal size (women's 8.5 = unisex 7).
Brand differences are extreme: A US size 9 ranges from 255-281mm across manufacturers, making size labels poor predictors of actual fit.
Your feet matter more than assumptions: Actual measurements and brand-specific charts work better than trusting gender categories or past purchases.
Some brands get it right: Companies like Black Tulip build truly gender-neutral shoes for different foot shapes, while others cling to outdated binary systems.
Footwear's future depends on designs that follow real foot anatomy instead of arbitrary gender labels, making shopping work better for everyone.
Gender-neutral shoe sizing confuses most people, even though nearly 30% of adults now buy clothing outside traditional gender categories. The issue goes beyond confusing labels. Wrong size and fit drive 53% of fashion returns, costing companies $25.1 billion yearly in processing fees. Men's and women's sizing systems put up walls when people shop for trainers, dress shoes, and daily footwear.
You probably want to know what unisex sizing means and how it actually works. Does EU sizing work better than US systems? Do unisex shoes run big or small? These questions don't have simple answers. This guide breaks down why traditional labels fail, how different sizing systems really function, and what brands like Black Tulip are doing to fix these problems with truly inclusive footwear.
What Traditional Shoe Labels Get Wrong
The Gendered Sizing Myth
Separate men's and women's sizing systems rest on shaky foundations. The US system offsets women's shoes by 1.5 sizes from men's, so a women's size 8.5 equals a men's size 7. Nobody knows exactly when this offset started or why it exists. Women's shoes typically measure about one full UK size smaller than men's shoes with the same numerical label.
Width classifications make things worse. A "medium" width for women registers as B, while men's medium is D. Specialized brands offer up to nine width options, but most stick to five: A through E, with A being narrowest. These random distinctions block people from shopping across gender categories.
Average Foot Shapes Don't Represent Everyone
Sizing systems calculate everything based on averages that ignore many shoppers. Research shows 76% of women have wider forefeet relative to their heels compared to 48% of men. Yet women's lasts are built narrower at the heel and forefoot, which contradicts actual foot measurements for three-quarters of female shoppers.
Shoe lasts evolved separately for men and women based on broad anatomical assumptions. Men's lasts provide more room through the instep and forefoot, while women's feature narrower heels and more defined arches. Athletic shoes for women have traditionally used scaled-down versions of men's lasts, despite documented differences in foot morphology throughout the lifespan.
Some women benefit from the extra cushioning in men's running shoes, while men with pronation issues find the larger toe box in women's shoes helpful. Half-sizes appear more frequently in women's lines, which helps men avoid the risks of oversized shoes. Brands like Black Tulip address these gaps with gender-neutral designs built for varied foot shapes rather than assumed gender categories.
Brand Inconsistencies Make It Worse
Sizing swings wildly across manufacturers, even within the same brand. You might wear a size 9 in one company and a 9.5 in another. Classic models like the New Balance 880 and Nike Pegasus can vary from version to version.
ISO standards govern shoe sizing and international conversions, but brands don't universally follow them. Different measurement methods, manufacturing processes, and allowances create inconsistencies even when the same system is used. Materials and construction methods influence fit as well. Treating size charts as guarantees rather than starting points leaves shoppers frustrated.
Understanding Unisex and Gender-Neutral Shoe Sizing
What is Unisex Sizing for Shoes and Trainers
Most brands default to men's sizing when they label shoes as unisex. This means anyone who normally buys women's shoes needs to do some math. The standard conversion requires dropping 1.5 to 2 sizes from your usual women's measurement. So if you wear a women's 8.5, you'll want a size 7 in unisex or men's shoes.
Black Tulip takes a different approach with their gender-neutral footwear. Rather than forcing conversions, they design shoes that work for different foot shapes without the traditional gender assumptions. Their system focuses on actual measurements instead of arbitrary labels.
How Does Unisex Shoe Sizing Work in Practice
Unisex trainers display sizes that match men's US measurements. Women shopping these styles should subtract 1.5 sizes from their normal size. A women's 9 becomes roughly a 7 or 7.5 in unisex sizing. CAT Footwear tells women to go down 2 full sizes from their regular fit.
Here's the reliable method: grab a piece of paper and tape it to the floor. Mark where your heel sits and where your longest toe ends, then measure that distance. Use this measurement with each brand's specific size chart rather than guessing at conversions.
Does Unisex Run Big or Small: The Real Answer
The fit depends on what you're used to. Women often notice unisex shoes feel roomier than their typical women's styles, while men with wider feet might find them more snug than standard men's shoes. Unisex shoes use a last that splits the difference between traditional men's and women's construction.
Width Considerations in Gender-Neutral Footwear
Width measurements stay consistent across the conversion. Unisex trainers typically default to men's D width, which equals a women's D-wide. Those who normally need wide shoes should size up half a size. Unisex lasts work well for average to slightly wider feet but can feel restrictive on very wide feet.
Is EU Shoe Size Gender Neutral Compared to US Systems
EU sizing runs on one scale from 34 to 51, making it genuinely unisex. US sizing keeps separate men's and women's ranges with different numbers. European measurements eliminate the guesswork since each US size maps to a specific EU size regardless of gender labels.
Real Challenges Shoppers Face Today
Finding Your Size Across Different Brands
Two-thirds of people walk around in poorly fitting shoes. Poor measurement habits aren't the only problem - manufacturers can't agree on what a size 9 actually means. Take internal shoe length: the same US size 9 varies from 255 to 281mm depending on the brand. Width tells an even messier story, with men's US size 9 (Medium D width) ranging from 86.2mm to 102.4mm across different companies.
Each brand builds shoes on different lasts. Nike's Mercurial football boots use completely different forms than Air Force 1s, so your size 9 in one feels nothing like your size 9 in the other. Brooks running shoes tend to run shorter than most brands. Your usual size becomes meaningless the moment you switch manufacturers.
The Trainer Market: Nike, Adidas, and New Balance Approaches
Nike keeps the traditional 1.5 size gap between men's and women's shoes, showing both conversions on unisex styles. Different Nike models still use distinct lasts even when they share the same size number. Adidas adds to the confusion by slapping men's sizing on unisex items without explaining the switch. New Balance markets gender-neutral collections but sticks to the same men's-based sizing everyone else uses.
Limited Options in Formal and Specialty Footwear
Dress shoes remain stuck in gender boxes. Tomboy Toes fills a gap by making men's dress shoes for smaller feet, helping people most retailers pretend don't exist. Standard trainer releases run UK5.5 to UK12, leaving anyone outside that range out of luck.
Why Some Shoe Styles Still Resist Gender-Neutral Sizing
Money stops progress cold. New molds for smaller sizes cost manufacturers plenty, and smaller brands skip them when demand looks thin. Black Tulip sidesteps these problems by building truly gender-neutral shoes that work for different foot shapes across broader size ranges.
What Brands Are Getting Right (And Wrong)
Brands Leading the Way in Inclusive Sizing
Wolf & Shepherd spent two years developing their Cruise collection with replaceable footbeds in three sizes. New Balance embraces gender-neutral fitting across multiple sneaker ranges. Wildling Shoes eliminates binary gender labels entirely, offering wide toe boxes that accommodate all feet. Hoka and New Balance provide certain models in wider widths. Jimmy Choo extended sizes for larger feet, while Puma offers traditionally-gendered colors like pink and lavender across all ranges. Black Tulip designs truly gender-neutral shoes built for varied foot shapes rather than assumed gender categories.
Common Mistakes Even Progressive Brands Make
Brands oversimplify their customer base when they design for "average" users while neglecting 20% of shoppers who fall outside standard measurements. Zalando launched gender-inclusive marketing campaigns, but searches for "gender-neutral" returned no actual products. Brands create clothes for no one when they skip involving trans and gender non-conforming people during development. Non-stretch jeans produced horrendous return rates for Zalando's genderless line.
Simple Solutions That Work
Adjustable elements work. Designer Jeanne Friot's belt-integrated designs became bestsellers when they fit three different body sizes. Data-driven sizing reduces returns when brands analyze purchase history and customer feedback. Stretch materials placed strategically improve fit across body types.
Conclusion
Gender-neutral shoe sizing shouldn't be this complicated, but traditional labels and brand inconsistencies create unnecessary barriers. The good news? You don't have to settle for ill-fitting shoes anymore. Black Tulip offers gender-neutral shoes designed for varied foot shapes rather than outdated gender categories. Focus on measuring your actual foot dimensions and consulting brand-specific size charts. With the right approach and brands that prioritize inclusive design, you'll find footwear that actually fits your feet.
