Just bought these and tried them out for a few days. The cushion and sole are nothing special. Not particularly comfortable but not uncomfortable either. The strap however is not comfortable. The thong that fits between the toes is wide enough  and stiff enough the if your wearing them for a long duration it will cause some irritation. The material for the strap is just as irritating. I have narrow feet and the strap looks like its for a foot twice as fat as mine. Ill keep them and use them sparingly when Im expecting to get my feet wet, but Im a bit disappointed. It looks decent except for the looseness of the strap.

Heres my recommendation: if you're looking for something cheap buy a $.99 pair from Walmart. If you're looking for something nice spend $30-$40 for a shoe with a neoprene strap. This shoe would be 100 times nicer with a nicer strap.
