If you're a women, LL Bean is selling some very thin
sandals for $12.99 with free shipping through tonight? The normal sale price is $19.99.
I have the sandals in navy, gold, and silver. They're flexible thin and have no real raised heel. They're 8mm thick and lightly if at all cushioned. The piper sandals also come in metallic silver and a metallic gold color. Just search for piper sandals on the web site and you should find it.
Oh yeah, they run big. I wear 7.5 in shoes (KSO 38, classics 39) and the size 7m fits well. It's not a very wide sandal, but it not super narrow either. They're cute summer sandals.
Edit: I got my flip flops today and ran smaller than the t-strap sandals. They weren't very comfortable between the toes and the footbed wasn't leather like the sandals. So the flip flops aren't as good or nice as the t-strap sandal and were sent back.
