Sorbothane insoles were first sold in America in the 1980s, having been produced by Dr. Maurice Hiles. Dr Hiles had performed numerous experiments to test the effect that walking and running have on the body. Heavily invested in his investigations, the doctor had electrical probes implanted into his own leg which would measure the impact these forces have. Having gathered the results, Dr. Hiles produced material which would absorb the dangerous shock waves and so Sorbothane insoles were born. Since then, Sorbothane has produced a huge variation of products which help to protect the feet from the effects of impact shock. One such product is the Sorbothane Full Strike Shoe Insoles. These lightweight, comfortable insoles are ideal for sporting activities where the whole foot is impacted by shockwaves. The insoles feature the unique viscoelastic material designed by Dr Hiles which offers supreme protection to the feet, ankles and knees. Another great feature of these premium insoles is that they are durable and designed to last.
