All insoles are sold in pairs.
 
KidZerts children's full length arch support insoles are cushioned more than the 3/4 insoles, particularly in the forefoot area. Like the KidZerts 3/4 length, they're designed to improve the health of children's feet by providing arch support and heel stabilization to improve balance and posture all while reducing discomfort from overpronation, flat feet, foot fatigue, plantar fasciitis, and arch pain. KidZerts full length insoles have the same wear-moldable technology and anti-bacterial top cover as the 3/4 insoles, which means that they'll conform to the natural shape of each individual foot and help minimize smelly feet since the top cover kills over 650 different types of bacteria. KidZerts children's full length insoles are recommended for kids' shoes that have removable footbeds, athletic and running shoes, and shoes with generous toe box designs.
