米国女性からEU変換ツール

US Women's shoe sizes run approximately 1.5 sizes larger in number than US Men's for the same foot length, with US Women's 9 corresponding to about 25.4 cm foot length. This offset often causes confusion when shopping for unisex or athletic shoes. US Women's 9 ≈ US Men's 7.5 ≈ EU 40 ≈ UK 6.5.

EU shoe sizes (also called Continental or Paris Point sizes) use a scale where each size increment equals 2/3 cm (6.67 mm) in foot length, making EU 42 approximately 26.7 cm. The EU system is used throughout continental Europe and is the most common international standard. Converting between EU and US/UK sizes requires knowing the foot length.
