Questions about Shoe Size Converter
How do I measure my foot for the right size?
Stand on paper in the evening, mark the heel and the longest toe, and measure the distance in centimetres. Enter that length in the cm system; measure both feet and use the larger one.
Are these conversions exact?
They are approximate retail standards. Brands and shoe lasts differ, so always check the maker’s own size chart and choose the larger size when you fall between two.
