Cycling Shoes

A technical shoe designed to deliver superior comfort and durability for aggressive all-mountain riding. The seamless upper provides hours of comfort in or out of the saddle. A new sole featuring a nylon composite shank and Vibram rubber provides maximum grip, longevity, and pedaling stiffness. - Advanced 3-Layer Seamless Composite Upper delivers all-day riding comfort and durability - 1:1 Anatomic Buckle Closure System reduces hot spots and removes pressure from your instep - Low-cut construction for a light, fast fit and feel - Nylon composite shank for efficient power transfer and off-the-bike versatility - Lightweight EVA midsole for off-the-bike cushioning and all-day comfort - Aggressive lugged Vibram Megagrip compound outsole for superior traction and durability - SPD Compatible - Weight: 398g (size 40)

This shoe can transition from an indoor cycling studio to a gym workout and out to the coffee shop. The seamless mesh design has a terrific feel and maximizes breathability. Using our experience with cycling shoes, we’ve built in stiffness for comfortable pedaling, but left enough give in the toe area to walk normally. A single strap makes for quick adjustability, while the recessed cleat mount keeps metal cleats from clicking on the floor. - Booty construction with single strap for easy on/off in busy studio environment - Mesh forefoot for additional breathability and comfort - 3/4 length composite shank provides pedaling stiffness without sacrificing walk-ability - Easy to walk recessed-cleat design - 2-bolt SPD cleat compatible

The Flow meets the needs of riders who want a shoe that performs well on the bike and can handle a season of abuse. Wide-set lacing allows a very adjustable fit and a lace lock keeps your shoestrings away from your drivetrain. The secret to this shoe's success is the grippy performance rubber compound combined with our chevron-shaped PinLoc tread pattern to keep your feet firmly planted and in control. - Traditional lace closure for a precise fit and all-day comfort - PinLoc Outsole with performance rubber provides outstanding grip to keep you in control - Lace lock keeps laces safely away from your drivetrain - One-piece midsole and outsole for excellent shock absorption on hard landings - Designed specifically for flat pedals (not clipless compatible)

Mountain bikers who ride flat pedals deserve shoes with as much advanced technology as those who ride clipless, which is why we developed this flat pedal shoe with a BOA Fit System to provide unrivaled fit and comfort. The redesigned Launch Flat builds on everything we love about riding flat pedals: freedom of movement, versatility, walkability; and it kicks all the downsides to the curb. The Launch uses a lightweight, quick-drying upper, constructed from durable Cordura fabric made with recycled content. We partnered with the rubber experts at Goodyear to develop a tread compound that's both sticky and long-wearing for our PinLoc Outsole. The result is a sole that is wider for more surface contact and uses a chevron tread design to capture pedal pins, keeping your feet planted and in control. - BOA Fit System with L6C dial lets riders fine-tune fit while they ride - PinLoc Outsole with premium Goodyear rubber provides outstanding grip to keep you in control - Seamless, perforated upper is breathable and quick-drying, made with durable recycled Cordura - Nylon shank provides stiffness for pedaling comfort and efficiency - Reinforced toe box for added protection - EVA foam midsole cushions impacts - Designed specifically for flat pedals (not clipless compatible)

If you find yourself digging dirt jumps or railing loose and loamy trails, a bit of extra ankle protection can be a great thing. That's why we made the Launch Mid WRX. This mid-top flat pedal shoe is constructed on the same platform as the Launch Flat, with added ankle and heel protection and a gusseted tongue to keep out dirt and debris. Because trail conditions can be highly variable, the Launch Mid WRX uses a water-repellent membrane to keep the elements at bay. Laces can be a hassle when covered in mud and grime, so the Launch Mid WRX relies on a BOA Fit System to make fit adjustments a breeze. The rubber experts at Goodyear developed a compound that is sticky and long-wearing, which we mold into our chevron-shaped PinLoc tread to keep your feet planted and in control, even in slippery conditions. - PinLoc tread pattern provides a secure pin engagement - Mid-top design with ankle strap and gusseted tongue provides extra support and keeps debris out - WRX treatment sheds water - Water-resistant Cordura fabric is durable and helps shed moisture - Reinforced toe box for added protection - BOA Fit System with L6C dial lets riders fine-tune fit while they ride - Goodyear premium rubber compound is grippy and long-wearing - EVA foam midsole cushions impacts - Designed specifically for flat pedals (not clipless-compatible)
