It starts with a great fit: A new roomier toe box offers more space for your toes to spread out, and the Endofit tongue hugs the foot for a wrap-around, glove-like fit. It also means the tongue can’t move around in the shoe, so it won’t slide sideways during climbs. The Boa® Fit System IP1 is adjustable in 1mm increments so you can find the perfect fit for your foot. And the laser-cut, ventilated upper regulates foot temperature.
For exceptional performance, the ultra-stiff energy carbon outsole drives all your power into the pedals. And the lateral and medial TPU frame keeps your foot hold secure in all positions, further boosting your efficiency.
