The problem with these shoes was the smell!  The ones I received had such an incredibly strong odor of rubber that I could smell it already coming through the unopened package in my mailbox!  Unfortunately, even after washing they smelled terrible.  My girlfriend suggested that I put them outside in the sun, hoping that it might somehow burn off the odor.  Apparently someone either stole them or threw them away (perhaps both), but that's the only reason that I didn't return these.  Great price, but only useful to anyone who can take the strong smell.
