ezCycler® custom orthotics are designed to work in all types of cycling shoes, clip on or not. They will enhance the bio-mechanical function of a cycling foot supporting the forefoot and reducing the metatarsal pressure that can become a problem during long rides. This orthotic is strictly for use during the cycling activity. The foot has a different function during cycling compared to walking and running, and need a different level of support. You will lead the pack with less effort because your feet will be less stressed and ready to go the distance.
