Soletech now offers Rigid-Flex and Semi-Flex insoles for athletes and others who will benefit from extra arch support. Both the Rigid-Flex and Semi-Flex insoles are lightweight and slender, with a streamlined shape. The new insoles are composed of injection-molded polyester and are thermomoldable to facilitate an optimum balance of flex and support. The Rigid-Flex insole has a firm rigid base that helps form and support the arch, while the Semi-Flex insole has more flex, or “give,” in the arch, to improve comfort for patients with a sensitive arch while still providing support. Available in seven unisex sizes.
