Glycerin 22is a combination of softness and cushioning. This year's edition uses our most advanced foam - DNA TUNED, which provides maximum cushioning when landing on the heel, while when taking off from the toes we will feel a dynamic take-off. The upper has been completely refreshed to provide you with an even better fit.
The new RoadTack rubber is lightweight, flexible and made from a blend of recycled rubber and silica.
