OK, here's how it was for me.  I wear 10.5, ordered size 11, they came, I opened the package, looked at them, confirmed that indeed they are a most peculiar looking shoe ( one that I swore I would NEVER wear), put them on, and then forgot they were on my feet for the rest of the day. How is this possible? Have you ever put on a pair of shoes and really forgot you even had them on?? I wear Stacy Adams dress shoes when I must dress up (the most comfortable dress shoe ever) and Rockport Pro Walkers other times, but this incredible shoe will now to be worn whenever I can get away with it.  I don't care what the fashion police think. Croc's rock!
