Patented in 2019 rebounding ergonomic custom fit polyurethane inserts for sandals, mules, kitten heels, slides and sports footwear provide all around comfort in four ways for all shoes with a tiny forefoot insert ¼” high permanently bonded to insoles to stabilize feet in shoes. 1.Maintains weight at the heel end of footwear making for better fitting dress shoes and more foot control during vigorous movements in sports shoes 2.Cushions the ball of foot with rebounding foam from downward pressure. Polyurethane never flattens so you get a fresh springy step each time 3.Prevents feet slipping forward in the shoe, stops bruised toes in marathon running, stops pinched nerves that cause forefoot pain and heel blisters from runners that gap at the heel end and slides or mules that fall off. 4. Stabilizes feet in shoes with the ergonomic design of the toe grip that allows for normal propulsion and balance resulting in more fun and better play, and less tired feet and legs from quick stops and starts during court sports. . The custom fit ball of foot forefoot cushion fits shoe sizes 7 to 10 women, and up to size 8 for men. The inserts are ideal for under 2” pointy toe kitten heels, cowboy boots, low heel sling back sandals, dress boots, dance shoes, mules and slides. The tiny tan colour 2” x 3” x ¼ “inserts take up minimal space, never crowd the feet, and hide discreetly underfoot. You can wiggle your toes even while stepping down. The inserts bond permanently to insoles to ensure effective functioning and no slippage of the inserts during vigorous foot movements. Walking, running or skating are less tiring, footwear is less wobbly and motion is more natural because your toes function effectively for propulsion and balance so both you and your shoes last longer walking or playing any sport. The inserts are not slippery or hard like gel inserts, or bulky and easily flattened like memory foam inserts. The inserts can be cleaned in place with water and dried with paper towels. For foot care use only plant-based foot creams, because petroleum-based oils such as baby oil will dissolve the adhesive.
