For optimal power transfer For maximum riding comfort and a secure fit, we put on our Sidi Shot 2S road running shoes and hit the road. C-Boost carbon outsole ensures no power is wasted when we press the pedals hard and the unique clasp system distributes pressure evenly across the leg providing comfort while driving regardless of distance. We also like the integrated heel cup which is reinforced to minimize deformation after long trips and its anatomical shape stabilizes our foot when pedaling.
