Discover insoles for boots, shoes and trainers at ShoeMed. Inserts can offer support for Plantar Fasciitis, Arthritis, fallen arches, and more. Gel shoe inserts use micro-bubble technology within the impact zone to help reduce impact through joints and increase shock absorption. Orthotic insoles are anatomically shaped, helping to relieve the forefoot and cushion the heel during long periods of walking and breathing. Many podiatrists recommended insoles for flat feet to provide comfort and relief.
