The ZS1-RC features a carbon sole made of multidirectional carbon fiber (with a silver coated finish) for unbeatable rigidity and power transfer. The tops are made with synthetic leather-like LivePore micro-fibre and finished with a protective and easily cleanable glossy white coating. Ample ventilation is provided with micro-fiber HighFlow mesh. A micro-ratchet lever provides for millimeter-precision adjustment along with a double Velcro strap for fine-tuning the fit.
