The first generation of Protalus's T-100 Insole. Proven Better Alignment: Our premium shoe insoles align your body by supporting the subtalar joint, preventing overpronation or oversupination. This alignment reduces stress on the ankles, knees and hips Patented Technology For Your Feet: Protalus' patented technology, known as the Tri-Planar support system, revolutionizes the way insoles work and feel. Created to reduce unsafe lateral ranges of motion, the technology utilizes counter forces to align the ankle with the heel for ultimate foot support. Ideal for Standard Size Shoes: The T-Series replacement insole is designed for running shoes, dress shoes, oxford shoes, and other casual shoes like Vans, Nike Free's, and Sperry shoes. Scientifically Proven: Protalus insoles improve alignment of the ankle by 31% when compared to generic stock shoe inserts The first generation of Protalus's T-100. Thinner than the M-series, these insoles feature a low-profile shape designed to fit in shoes with less volume. Our T-100 provides more moderate support for the ankle joint, suitable for those needing a combination of cushioning and alignment, with shoes that may not have the space to fit (allowance for) the M-Series. Pairing our patented TRI-Planar technology with our conforming heel cup, you can do what you love without sacrificing comfort. Whether you’re constantly on the move or simply need a little more support, experience your world and do what you love in alignment with Protalus.
