Case 1: Performance - Single unit (one full sole insert) cut-to-size is placed under the insole of the RIGHT skate or shoe. Enables you to skate with correct posture which improves performance. Mitigates lower back pain, prevents ankle twisting and relaxes hamstrings. Improves upper body stability and leg strength. Used by skaters, skateboarders, runners, cyclists and those who use Heelys.

Case 2: Growing kids - PostureFLEX inserts (2 - one for each skate/shoe) are cut and fit below the footbed or liner of each skate or shoe. This tightens up the entire skate / shoe! Now you have a tight fitting skate that will respond better and feel better, making all the tricks easier to do. Once the kid grows again, simply lift the footbed or liner and take the Postureflex inserts out of each skate. Replace the original skate/shoe liner / footbed and off you go.
