The G8 Performance Heel Wedge Kit helps you correct alignment issues and can help transition from one arch height to another. These heel wedges seamlessly click into G8 Performance 2620 orthopedic insoles, making them incredibly easy to set up. They are perfect for anyone whose feet do not follow a straight line, people with rear foot misalignment, or people who want to create smaller increments between arch heights. The kit comes with six wedges in three different heights. Each height features two wedges, one inward and one outward facing. These are non-stackable true wedges which means that the zero portion of the wedge stays constant regardless of wedge height. Anyone looking to correct the alignment of their feet on or off the bike can benefit from the G8 Performance Heel Wedge Kit.
