## Description

Our clinically proven j1 insoles are a patented 3-point design providing true support, not just cushion for flat feet. They were developed by Dr. Lorri Riley, a podiatrist for over 20 yrs. The patented j1 insoles for flat feet are designed for people with flexible flat feet to bring your arch back up to its neutral position while correcting the foot in all 3 areas: the heel, arch and forefoot. J1 insoles are made of a semi-rigid medical grade plastic much like the plastic used for prescription orthotics. This material allows for the natural shock absorption and flexion of the foot. J1 Slims are medical-grade shells without the top covers, and are designed to slip beneath the insole that came with your shoe. J1 slims are perfect for runners or people wearing dress shoes who want a strong insole without the added bulk of traditional insoles. J1 insoles are made in USA.

As effective as those ridiculously priced insoles from one of those retail shops and they look about the same. Save your money first and try these to see if they work for you before dropping $300+ at one of those specialty stores.
