Viva is thin enough to fit in almost any shoe. Viva is made of prime quality cowhide tanned with herbal extracts for the optimum shoe climate. Viva insole has an orthopedic design which helps prevent and relieves “splayfoot” by relieving pressure on the ball and arch of the foot. Viva is recommended for those who suffer from Plantar Fasciitis.  Viva features a sturdy support for the longitudinal arch and a built-in orthopedic insert/pellet for the latitudinal arch (metatarsal). These supports allow the foot to maintain and to regain an anatomically correct position. Viva also has a heel pad which relieves pressure and impact on the heel. Viva has a purifying active carbon filter to help prevent foot odor and an anti-bacterial treatment to help prevent the growth of bacteria and fungi.
