I wear 11 so that is the size I ordered.  Toes rubbed.  So I sent back and exchanged for 11.5.  Toes on one foot still rubbed.  Finally had more success with 12 though the full shoe feels a bit long.  Nevertheless, it works fine.<br /><br />All that to say, is that it is workable but not a perfect fit for my foot.  Nevertheless, it is a great shoe that works and for a little over forty bucks, it was a great deal.  I went to the sports store and they wanted to sell me glow in the dark freak shoes for over a hundred.  The easy Amazon exchange was a minor inconvenience.  After each size, I put it back in the box, printed a label, gave it to the UPS guy at work and found the money back into my account within a few days
