Title: THEY DON'T WORK
Review: I'm an athlete with a 40+ inch vertical and seen the spring bak insoles and wanted to see how high I can jump with them and they don't work and anybody that says they do is lying they tell you to put the spring bak in your shoe under your regular insoles and your going to run faster and jump higher the only thing I got was foot pain because the spring bak makes your regular insole unbalanced.
