I absolutely love these sandals. The delivery time was super fast (about 3 days sooner than expected) and they were in perfect shape. I've been wearing them near constantly and they seem to be holding up really well and are much more comfortable than any other pair I have ever used. Reef uses two types of foam in their sandals, a firmer foam for the sole and a softer foam that eventually molds to your feet. The firmer foam also provides some arch support, it's not great but it's a lot better than what you usually get with flip-flops. On some sandals I've owned, the stalk (idk what it's actually called, it's the part between your toes) causes discomfort but on these the fabric they used is really comfortable and took no time at all to get used to.

I highly recommend these sandals, they're awesome!
