Children&rsquo;s Gel Sport Insoles for All Day Wear (Kids sizes 3-4.5) (Arch and Heel Support) &hellip; Kidsole's Sport Insoles are designed with soft fabric with a PU gel base. They are moisture-wicking, and highly breathable. The design of the insole is intended to cushion and massage the feet. Shock Reduction and Comfort  Weve gone through hundreds of gel shapes to get the perfect shape to minimize shock to the foot and comfort. CUSTOM FIT  This insole's size is: 8 in. long by 2.5 in. wide and will fit in big kids shoe size 3-8. This insole is designed to fit all shoes. It can be sized up against your existing insole, and then cut with a pair of scissors along trace lines for the perfect fit (See Photos). Our embossed cutting guide lines make our insoles suitable for many kinds of shoes and cleats. HEEL AND ARCH SUPPORT AND COMFORT  These insoles will provide extra arch and heel support with our tried and tested PU gel design. The gel helps to absorb pain-inducing shock and help eliminate aches and pains over time. Additionally, the gel base will prevent the insole from slipping inside the shoe.
