The "V-FLEX SYSTEM" is the ergonomic design of the upper on the ankle flex area. It allows a wider and more natural movement of the foot. The upper, in synergy with the lacing system, wraps the foot in an optimal way, offering the maximum comfort and support.
Thanks to the "V-FLEX SYSTEM", we have further improved the overall comfort of the shoe and the capacity of the upper to adapt itself to the movement of the foot, even when walking on steep routes with heavy packs.
