It takes a lot for a flip-flop to stand out from the crowd these days, but Okabashi has wowed us. Arch support and massage beads make these flip-flops comfortable to wear. And they are dishwasher safe. That's right. When they start to get gnarly, just throw them in the machine on high. But when a wash will no longer do, return your sandals to Okabashi, which will recycle the plastic to make new ones. $14.99 in a variety of colors at Okabashi.com or at major retailers including CVS and Walgreens.
