Cycling Shoes

The Trailcross Clip-In is the latest addition to the Five Ten Trailcross family, designed from the ground up with adventure at its core. Packed with all the Trailcross technology, this latest model provides clip-in performance on the bike and all-day comfort when hiking off the bike. The addition of the Clip-In model takes the range to the next level, making our award-winning design available to clip-in pedal users for the first time. The Trailcross range was built from the ground up, starting with the Five Ten dotted outsole with the addition of a recessed cleat to clip into compatible pedals. This was then refined with hiking in mind, bringing the additional ridged grip to the toe and heel. The Trailcross Clip-In is a lightweight and breathable shoe. With the need for the shoe to provide all-day comfort but also deliver across the contact points on and off the bike, the mid-sole EVA technology provides the necessary toe flex for hiking, without losing the all-important stiffness. The Trailcross Clip-In utilizes a hook and loop closure for added security and to reduce heel lift. Clip-in pedal users no longer need to compromise when planning their next adventure. - Lace & velcro closure - Breathable mesh - RPU overlays - Impact resistant toe box - Lightweight eva w/ hike a bike last - Stealth marathon

The S-Works Torch is the latest evolution of the winningest footwear in cycling. Using Body Geometry together with biomimicry, data science, and obsessive craftsmanship, we engineered a shoe so thoughtfully constructed that you'll forget you're wearing it. Leveraging data science, we refined every detail of the S-Works Torch's upper for improved fit and performance. The BOA cable is shifted down and angled, preventing lift on the ball of the foot and delivering power-enhancing structure while eliminating unwanted pressure or pinching. Adaptive materials allow natural movement of the foot where needed for comfort, while data-driven zonal reinforcement keeps the foot secured for crisp power delivery and optimal efficiency. Guided by more than 100,000 foot scans from our RETÜL fit data, we recognized that both a standard and a wide carbon base plate would best serve the spectrum of human foot shapes. An internal I-Beam adds stiffness and strength, eliminating the need for additional bracing. The result is a 20-gram weight reduction, enhanced efficiency, and immediate power transfer. Following RETÜL bio-mechanical data, we created an asymmetric heel cup that supports natural knee alignment and delivers the positive hold riders love while enhancing comfort by accommodating more room for the Achilles heel. The S-Works Torch is scientifically crafted to disappear on your feet and off the front. - New upper features reinforcement in key zones while also offering adaptive fit zones to create a disappearing fit on the foot. - Based on data gathered from Retul foot scans, the new base plate is 4mm wider at the ball than the previous generation of S-Works 7 shoe. - By optimizing its construction, the new carbon plate is 20g lighter than the S-Works 7. An internal "I-Beam" ensures it maintains the same stiffness as the previous generation. - An updated last makes use of Retul data to better match the shape of riders' feet, sloping more towards the lateral side to give a snug, close-to-foot fit. - Asymmetrical heel counter supports the medial side while removing material from the lateral side, allowing for a lower collar. - Updated BOA cable routing improves lockdown while reducing pressure across anterior ankle ligaments. - Independent alloy BOA S3-Snap Fit System for on-the-fly micro-adjustment, backed by the BOA Guarantee. - Titanium alloy cleat nuts can rotate to position pedal/cleats 5mm rearward. Three-bolt cleat pattern fits all major road pedals. - Non-slip, replaceable heel tread with internally recessed screws for security. - IMPORTANT FOR WIDE FIT—the new base plate is 4mm wider than the standard width (8mm wider than S-Works 7).
