These are high quality flip flops which have nice grip on the insole and pretty good one in the bottom. Specifically the wider toe area and the portion of the outsole that comes up to cover the nose of the shoe. it might push the price up and Im selfish that way :) but yeah, I would advise them to get these. Great pair of headphones for the price. It’s a cute little pouch to be sure, but emphasis on little. Mine was a two fold. A 2 star book from a 1 star seller I like having this to use when Im in the car or store. I have owned Crocs before with never a problem. The slipper is nicely made and comfortable.
