This insole features a durable rubber 154 bottom paired with a double-thick foam top. The top foam is 3/4 length, while the bottom foam is full-length, allowing more room for the heel and toes. With new dual-zone technology, it provides targeted support and responsiveness for enhanced comfort and performance.
Notice the rectangular shape, a design upgrade from the standard oblong oval, offering a better fit and more functional support for natural foot movement.
