Combining excellent ventilation with a secure closure, the CUBE SYDRIX shoe offers road riders both comfort and efficient power transfer. A glass fibre shank with ventilation channels and replaceable heel stud ensures every watt of the rider's power is transferred to the pedal, whilst the reinforced heel cap improves stability and heel lock. The single disc closure is quick and simple to use and, combined with an assymetric design, distributes pressure evenly for the best comfort and fit. The reinforced toe box improves protection in this vulnerable area, and a perforated waistlayer and NF Ergonomics insole ensure good ventilation, cushioning and pressure distribution for day-long ride comfort.
