With a streamlined look and the Boa® Fit System, this lightweight road shoe is inspired by mountains and the climbing stages of cycling's grand tours. The BOA® Fit System makes it easy to dial in your perfect fit. You can make instant micro-adjustments for a precision fit to improve your comfort and pedalling efficiency. The lightweight, breathable upper is made with supple synthetic micro-fibre and strategically placed laser-cut holes for added ventilation. The toe box is slightly wider for added comfort, and the Ortholite insole gives you long-lasting comfort and performance. Beyond its comfort and adjustability, the Cosmic Boa also delivers high-performance power transfer with a nylon and fibreglass outsole. It’s designed to be stiff enough for optimal efficiency but also comfortable for all-day rides.
