Brizza insoles can absorb up to 98% of the vibrations produced by the impact of feet with the ground. Using normal insoles negative energy propagates in the form of vibration that hits every neuralgic point, producing long-lasting microtraumas, often generating heel inflammation, tendinitis, plantar fasciitis, periostitis, stress fractures, joint pains in the feet, knees, hips, and the back up to the base of the skull. Brizza insoles provide a quick and effective remedy. The new Brizza ProGel insoles can be individually cut to fit all shoe sizes. Thanks to exceptional adherence on the lower side, once inserted they do not slide.
