Bauerfeind ViscoPed S insoles have softer comfort zones at the pressure points of your feet and are a must if you spend a lot of time standing or walking. These medical-grade viscoelastic silicone insoles incorporate softer areas under the ball of your foot to aid in the desired realignment of the metatarsal heads and to provide additional cushioning. They also have softer silicone in the heel region for shock load reduction with added cushioning on the medial side, the area most sensitive to plantar fasciitis pain. Shock is reduced throughout your feet, ankles, knees, hips and back. Ventilation holes allow for air circulation to prevent heat build-up. Comfortable and long lasting, may be easily trimmed for optimum fit. Sold as a pair to prevent leg length discrepancies and can be switched from one pair of shoes to another. They do not absorb odors or contain latex and are easy to clean with soap and warm water. Non-slip and can be worn in walking, sports, or work shoes, sometimes removal of the existing shoe insole is recommended. Made in Germany with the highest quality standards.
