Quite disappointed with my purchase. The sole is composed of 3 elements. A black outsole that makes the size of the foot, heel and two additional (red and black) which fit on the black sole. You can not use the 3 elements simultaneously. Your Talon out of the shoe, if you get to go do it! The black sole, used alone, is too thick if you want to "win" one size. It will do while in the red and black heels. It works but it's not comfortable. They have holes (to slot them into the black sole) which are very long and uncomfortable to even make sore heel. To win one size, I recommend the classic soles.
