The Mavic Cosmic SLR Red Blue Triathlon Shoes are designed for athletes demanding peak performance and versatility. Combining cutting-edge materials with innovative design, these shoes offer exceptional efficiency, support, and a precision fit that adapts to various foot shapes. Engineered to meet the rigorous standards of professional road racing, the Cosmic SLR delivers unmatched power transfer and comfort, making it the ideal choice for triathletes and cyclists alike.
At the core of this shoe’s superior performance is the patented Matryx technology, which integrates Kevlar woven polyamide to provide outstanding foot stability with minimal lateral movement. The full carbon Energy SLR outsole enhances stiffness while minimizing weight, ensuring that every pedal stroke converts your effort into forward momentum without loss. With a low-profile 6.5mm stack height, your foot sits close to the pedal, maximizing power and responsiveness on every ride.
Comfort and adjustability are paramount in the design of the Cosmic SLR. The 3D tongue and overlap construction of the Matryx upper create a snug, supportive fit that accommodates a wide range of foot sizes. The dual BOA Fit System IP1 dials allow micro-adjustments to fine-tune the fit during rides, while the low-profile ankle collar and integrated heel cup with pre-shaped foam secure your foot, delivering both freedom of movement and stability. These features combine to ensure comfort during the longest and most demanding triathlon stages.
Are these shoes suitable for all foot shapes?
The Matryx upper features an overlap construction and 3D tongue design that provide a comfortable, adaptable fit for a wide variety of foot shapes and sizes.
How does the BOA Fit System improve performance?
The dual BOA Fit System IP1 dials allow for precise micro-adjustments in 1mm increments, ensuring a secure fit that enhances power transfer and comfort throughout your ride.
What makes the outsole efficient?
The full carbon Energy SLR outsole is designed to minimize weight and rotational mass, combined with a low 6.5mm stack height to place your foot close to the pedal for maximum pedaling efficiency.
Can these shoes be used outside triathlon or road cycling?
While optimized for road cycling and triathlon, their lightweight and supportive design makes them less suitable for off-road or mountain biking disciplines.
