HappyFeet Massaging Insoles put your feet back in their healthy, natural environment. We stop pain and heal without expensive drugs or custom orthotics. HappyFeet Insoles are precisely filled with a vegetable based, food-grade glycerin. This Fluid Orthotic provides arch support, cushioning, massage and a variable, ever-changing surface for walking, standing and light impact sports. Massage - Alternating heel to toe pressure forces the liquid back and forth, providing a soothing massage, significantly increasing circulation to the feet. Improved circulation promotes quicker healing of existing injury from various lower extremity ailments. The absorbent cloth layers are a moisture barrier keeping feet cool and comfortable. HappyFeet are anti-microbial treated to resist odor and mildew. They are hand or machine washable. The glycerin acts as an insulator for cool feet in the summer and warm feet in the winter. Our insoles can be worn every day with any shoe. HappyFeet Insoles will last significantly longer than any other insole on the market.
