The Mavic Cosmic SLR White Triathlon Shoes represent the pinnacle of performance footwear designed specifically for triathletes who demand excellence in every race. Combining advanced materials with meticulous engineering, these shoes deliver an exceptional blend of power transfer, support, and comfort that empowers you to push your limits. Whether you’re transitioning from swim to bike or powering through the cycling leg, the Cosmic SLR ensures your feet remain stable and efficient, maximizing every watt of energy you produce.
Crafted using Mavic’s patented Matryx technology, the upper integrates Kevlar woven polyamide for ultra-lightweight yet durable foot support. This innovative material provides precise foot mapping, reducing unwanted lateral movement and enhancing stability. The full carbon Energy SLR outsole complements the upper perfectly, offering a stiff, responsive platform with a low 6.5mm stack height that keeps your foot close to the pedal. This design delivers a smooth, efficient pedal stroke that saves energy and improves your overall performance.
Comfort is equally prioritized with a 3D tongue design and overlap upper that adapts to all foot shapes for a snug, customized fit. The BOA Fit System IP1 dials offer micro-adjustability in 1mm increments, allowing you to fine-tune your fit effortlessly during races or training sessions. A low-profile ankle collar ensures free movement without sacrificing support, while the integrated heel cup with pre-shaped foam secures your foot to prevent slippage. Together, these features make the Cosmic SLR a versatile choice for triathletes seeking durability, comfort, and uncompromising performance.
