Happy Feet insoles are an effective tool to help customize your shoes to work with the mechanics of your feet. The fluid filled insoles shift with your bodyweight to create a customized fit and give you a little extra cushion to help with everything from stride and posture to high arches and heel pain. Happy Feet insoles also help correct improper weight distribution in your feet and absorb shock to alleviate joint pain. Plus you can easily swap out your insoles as your needs shift and evolve.
