This is my second pair of heavy duty crocs. The first pair had a strap that was badly designed. Even at maximum size it was way too small. These are great. The soles are thicker than usual so I can wear them when it is wet outside without my feet getting wet. I notice that these have larger than usual heels. After a couple of days I got used to them but you might want to reconsider if you have sensitive feet or heels. Generally I only wear my crocs. As a result they get a lot of wear. They seem to be holding up just fine so far.
