ShoeSizer: Size Converter

ShoeSizer turns any shoe size into US, UK, EU, JP and centimetres, so you can buy the right size abroad.

Standing in a shop overseas with a size you do not recognise? Dial in the size you already wear, or measure your foot in centimetres, and ShoeSizer shows the match in every system for men, women and kids. Everything runs on your iPhone, so it works with no signal.
