Source: Alpinestars official auto shoe and kart shoe size guides (US 2½–4½, 5½, 6½, 11½ and 12½ come from the kart shoe chart). Our size options are US sizes. Measure the longest part of your foot in cm and choose the size whose foot-length range contains it.
Sizing is from the manufacturer and varies between brands. Measure yourself and compare against the table rather than ordering your usual street size.
