I bought these for my husband. He kept complaining that I had crocs that were solid and he didn't. So I saw these and took the opportunity to get him a pair. He has the ones with holes in them that he's been wearing since he was in Afghanistan. He wears the new ones when he heads over for his physical therapy which he's almost done with. Of course now that the weather has finally started to warm up he'll probably go back to the ones with the holes in them.  He said the new ones keep his feet warm which might not be good in 80 degree days. Guess now I should get some with the holes to keep my feet from being to warm.
