When we want to go fast (like, super fast) we pull out the stiffest shoe we can find for the most efficient power transfer. With Gaerne, that's the Carbon G. Stilo Cycling Shoe. A lightweight full carbon sole makes for efficiency that's hard to beat, plus a stiffness index of 12. The optimized carbon fiber weave ensures every watt of power is transferred into the pedals, and the stability of the foot is increased due to the shape of the sole in the plantar arch area. Four air vents enhance ventilation inside the shoe, too, so we never feel like we're overheating on our ride.
