I normally wear a size 45(11) but I like to buy a size up just to be safe. These are just plain ridiculous. First off, the tag says 12/45 which are two separate sizes. Weirdly enough, it is neither. Being so small I think it's actually a 10.<br /><br />Add to the fact that it cost me $50 to ship a $30 item to Nigeria, that made it all the more frustrating.
