I never thought I'd pay $59.00 for a pair of flip flops but I did when I purchased the Orthoheel Women's Tide Thong and they are worth every penny of it.  I wear them at home, all the time.  I wear a 7-/2W and since they do not come in W, I ordered the 8 as suggested-not the way to go though!  When I saw the Women's Kinetic Thong, I decided to purchase as I really liked the look.  I ordered those in a 7 and am much happier with the size although I must say I like the support in the Tide much better.  I am keeping them but would not purchase them again.  I'll stay with the Tide and order the smaller size. I would rate the Tide Thong at 5 stars.
