The size 1.5 to 2.5 4Kids Orthotic Insole is an excellent solution to quickly and comfortably combating flat feet developing in young children.Made from shock absorbing EVA, the orthotic insole uses a triplanar wedge that is directed against the medial arch of the foot to increase the calcaneal inclination angle preventing a number of foot related conditions. The 4Kids Orthotic Insole helps to maintain the stability and support for the foot as well as controlling the internal leg rotation associated with sub talar joint pronation and thereby reduces symptoms such as knee pain. Prevention of the collapse of the medial arch will reduce the strain on supportive ligaments and other soft tissues, thereby allowing the child to enjoy running and walking pain free. The 4Kids Orthotic Insole is designed to work in conjunction with a supportive yet flexible shoe, allowing for normal freedom of movement prior to the foot achieving heel toe walking. The anti-bacterial top cover is incredibly hygienic and can also be cleaned with a sponge and soapy water to prolong life expectancy of the insole.
