Viva High is identical to Pedag Viva except that the longitudinal arch is higher than average. 20-25% of people have pronounced longitudinal arches (hollow feet). Abnormally high arches are more common than low arches and can lead to more foot problems too. Viva High prevents fatigue and minimizes pressure points. Helps prevent and relieve Plantar Fasciitis. People with high arches often put excess pressure on their forefeet. Viva High has a metatarsal pad which reduces forefoot pressure which helps prevent and relieve Metatarsalgia, Morton’s Neuroma, etc. A heel cushion helps absorb shock when active. Finally, Viva High is made of the finest, durable, vegetable tanned leather and uses latex free, active carbon to neutralize odor. Viva High is thin enough to fit in almost and shoe or boot. High quality natural materials allow the foot to breathe and keep your shoes fresh. After wearing remove from shoes and air overnight.
