Measure your feet: ICEBUG recommends measuring both feet while standing, from heel to longest toe, as precisely as possible in millimetres. Add 3–5 mm if you plan to wear thick wool socks.
Important: ICEBUG explicitly states that different shoe models may use different size charts. The chart on the specific product page therefore takes precedence over this general conversion.
