The Grey EVA foam used to manufacture the Pro11 Insoles provides comfortable support. Not too hard underfoot, these insoles are ideal for first-time orthotics users. The Pro 11 wellbeing Duo tech layered 3/4 insoles provide cushioning under the first metatarsal bone to reduce pressure and shock in this area of the foot during propulsion. This helps to relieve pain and discomfort in this area. This cushioning also allows plantarflexion of the first ray and facilitates the Windlass Mechanism, which stabilised the foot during propulsion. Pro 11 wellbeing Duo tech layered 3/4 insoles are made up of An Eva base and a mid foam layer which has the Metatarsal raise in and a soft velour top covering is also added for extra comfort. The Duo tech layered 3/4 insoles provide support to relieve plantar fasciitis and correct over pronation to improve the natural posture of your feet and your lower limb alignment. The three-quarter-length of the Pro11 3/4 Insoles for Plantar Fasciitis and Over-Pronation makes them ideal for most men's and women's shoes, including narrow and pointed-toe shoes, and they are a comfortable option for first-time orthotics users. The deep heel cup incorporated in these insoles provides added stability. The cushioned recess built into the lateral outside border of the heel cup reduces the shock of heel strick, decreases the velocity of rearfoot pronation and decreases shoe wear on the outside of the heel.
