Convert shoe sizes between UK, US Men, US Women, EU, and foot length (cm). Conversions are approximate - sizing varies by brand, so check the brand's own chart before buying.
India uses UK shoe sizing. This table is for adult sizes and is built from the standard size formulas described in
Wikipedia's Shoe size article: UK = 3 x last length in inches - 25; US Men = UK + 1; EU (Paris points) = 1.5 x last length in cm. The last is the shoe form, about 2 barleycorns (1.7 cm) longer than the foot, and the cm column here is the FOOT length, not the last length. US Women is US Men + 1.5, which is what
Nike uses; the older US standard scale uses +1, and other brands differ. Checked against
Nike's men's-based chart: UK, US and foot length agree on the rows compared, and EU can differ by about 1 size. Sizing varies by brand, so check the brand's own chart before buying, and measure your foot in the evening.
