I looked into these on the Crocs website before buying, they claim that they are roomy and if you want half sizes, to order the size down.  However this is not true, I wanted extra room, so I ordered size 11, like my boot size and my toes touch the front.

The width is very roomy and that is the good part.  However, the pair I received were defective, the left shoe is visibly shorter than the right and because the right was barely wearable, the left was impossible to wear.

I returned this pair and am waiting for the replacements, hopefully the new ones are not defective, or else I will have to order the next size up.

Over all, I like the look and feel of the shoe, just wish they fit as promised.
