Elite-level carbon fibre insole engineered to transform hiking performance through directional support technology. Featuring Carbitex® M3 Monoflex construction that only bends in one direction, it resists the extreme plantar flexion position when hiking to provide a stiff base for straighter leg position and more leverage while decreasing strain on ankle ligaments and calf muscles. At just 60g, this ultra-lightweight insole reduces fatigue, prevents injury, and allows you to hike harder for longer. Compatible with X and Performance dinghy boots.
