Fit by brand

Brand Shoe Size Guides

Conversion charts are only the starting point. Brand shape, width, material and category can all change how a shoe feels on foot.

Nike

Nike sizing is often consistent for trainers, but performance shoes can feel snug through the midfoot or toe box.

Adidas shoes are usually predictable, but classic silhouettes and performance models can fit differently.

New Balance is useful for shoppers who care about width, because many models are available in multiple width options.

Dr. Martens boots and shoes can feel firm at first, so length, width, and break-in expectations matter.

Birkenstock fit depends heavily on footbed length and width, so EU size plus narrow/regular width is important.

Clarks kids sizing is built around growing feet, so measurement and width are more important than a straight conversion.

ASOS sells many brands and own-label styles, so the safest approach is to check the product category and returns guidance.

Zara footwear is trend-led, so shape and material can affect fit as much as the size printed on the shoe.
