UIN insoles are made of soft and breathable OrthoLite material that provides a comfortable fit and sensory stimulation. Soft RPS Cushion with the responsive technology applied is designed to deliver massage experience and exceptional comfort during both static and dynamic activities. Soft external Cushion elements stimulate feet gently, while the inner part of the foam prevents insole compression. Unlike traditional cushion, UIN RPS insole compresses less than 5% across the product’s lifetime, providing long-lasting fit, performance, and comfort.
