With the Recon 1.0 our goal was simple - put S-Works Recon-inspired performance in a very accessible package. Easier said than done, but we've created a shoe with Body Geometry comfort and efficiency in a durable, dirt-focused shoe. So yeah, mission accomplished. Using our exclusive STRIDE toe-flex technology, the nylon outsole uses a TPU-injected forefoot for natural movement off-bike, while still providing a stiffness index of 6.0 for in-the-saddle performance. The Recon 1.0 is a double threat - efficiency at the pedals with comfort and confidence off bike. To create traction off the bike in wet or dry, gravel or dirt, we've covered the nylon outsole with our SlipNot compound. We've also lifted the heel for an even more natural feeling while walking. Three Velcro closures make slipping into the Recon 1.0 easy, and creates a fit designed for all day comfort and performance, whether your ride calls for open gravel, twisting single track, and more than your fair share of hike-a-bike. - Body Geometry sole and footbed are built with purpose and backed by science to boost power, increase efficiency, and reduce the chance of injury by optimizing hip, knee, and foot alignment. - Injection STRIDE toe-flex technology allows for natural toe movement off-bike but remains stiff for pedaling (stiffness index 6.0) - SlipNot rubber tread for confident traction on all terrain. - Two-bolt cleat pattern fits all major MTB pedals. - Approximate weight: 331g (1/2 pair, Size 42)
