I never would have bought pricey flip flops for myself, but my husband surprised me with a pair of Teva Mandalyns after he heard me talking to my mom (another flip flop lover) about what I had read about Teva's here on the DISboards. I LOVE them, they are so comfortable and I never got one single blister or sore spot even after wearing them in the parks for 12 - 15 hour a day.
I just got a great deal this morning on some at Sierra Trading post. They were really marked down and then if you have a discount code (which is not too hard to locate one online) you can save even more, though sizes are getting limited.
