Tuli’s patentend, multi-cell, multi-layer “waffle” design absorbs shock and returns impact energy just like the system naturally found in your feet. Upon impact, the waffle construction bears down and rotates with the normal motion of the foot to absorb the shock of walking and running; keeping your feet, knees, hips and back in alignment for maximum comfort and performance.
