Express Blue orthotics are designed to increases fit and comfort for the foot in any shoe. The moderate blue EVA foam provides a comfortable option for first time orthotics users.The arch profile provides support for the arch, improves alignment of the lower limbs and increases stability and balance. The cushioned heel cup reduces the shock of heel strike, decreases the velocity of rear foot pronation and decreases shoe wear on the outside side of the heel.Forefoot cushioning under the first metatarsal head reduces shock during propulsion allow plantar flexion of the first ray. This facilitates the windlass mechanism which acts to stabilise the foot during propulsion.
