I LOVE my Reefs..... I bought them three years ago when I left for school and the arch support was amazing. I still have them... three years later and the only thing they didn't survive was a piece of glass they saved my foot from! After two years, the foam was still so thick that the glass didn't go all the way through. And today, my foot is stitch-free because of them... I love my Sandy's, and I'll never buy another flip flop again!
