Size guide
Sizes and fit ranges vary by item. Find the relevant chart on each product page under Size & fit.
Measure your foot
Stand on paper, mark your heel and longest toe, then measure the distance. Measure both feet and use the longer one. Product pages show both centimeters and inches.
Baby and kids' sizes
Months and years are age guides, not shoe sizes. Choose by the listed foot length when available. 1–3T means approximately 1–3 years.
Adult sizes
US women's shoe sizes, original size labels, and one size are identified separately. Approximate EU and UK shoe references appear only where the item has an explicit US women's shoe-size range. Shoe sizing varies by brand. Fit ranges marked ≈ are estimated from age labels, shoe sizes or comparable styles and are not measured garment dimensions.
Knee highs and thigh highs
Measure calf or thigh circumference where the cuff will sit, plus the distance from heel to cuff. One size does not mean every leg circumference will fit.
