I have a few people asking me on the right shoe size. I can't give precise conversion to US size as it depends on the shoes. I recommend measuring your feet and refer to the conversion table. I had mine measured (in inches) and the shoe size came out right! :-) Please refer to http://shoes.about.com/od/fitcomfort/ss/measurefeet.htm for a step by step instruction on how to measure your feet and then refer to the conversion table at http://www.i18nguy.com/l10n/shoes.html. Happy measuring! =)
note: If you're wearing UK shoes or already knew your UK shoe size, simply refer to the conversion table to get your US size.
