Arch Support Sock for Thong (Flip Flops or Birks, not Underwear) Wearers!

Arch Support Socks for Thong Wearers! As exampled in the pic with the sock on my hand, the heel fits in the bottom black part. Then the sock where the arch is offers a little tighter support for the arches. And it has no toe in the socks, so free to wear thongs. Great for those that love their flip flops, but are having foot pain because of the lack of arch support.
