Redi-Thotics Ultra is a unique orthotic designed to reduce rear foot motion and increase midfoot stability. Ultra-thin and rigid, the Ultra cradles the arch, preventing medial and longitudinal arch bruising. The Ultra is designed with a Rylon support system, not a mass produced shell. Other features include a Pedura foam fill layer offering cushioning and breathability while the Barratex top cover is anti-bacterial and “breathes,” reducing heat build-up. Plantar fasciitis patients will also benefit from the built up medial arch and extra deep heel cup. The Ultra fits into most men’s dress shoes and most women’s casual shoes as its forefoot is easily trimmed to fit.
