Fizik Vento Ferox Carbon MTB ShoesPuty the power down and enjoy the instantaneous aceleration of the carbon-soled Vento Ferox Carbon MTB Shoes. They're the ultimate for the keen off-road racer. As you go full gas off the start line off a cyclocross race, plunge into the twists and turns of an XC mountan bike race or lean into the hard efforts of pushing the pace of a gravel event, the Vento Ferox Carbon MTB Shoes get you upro speed with minimum fuss and maximum efficiency. Tear up the TrailsWhen you're pushing the pace you don't want unnecessary bulk or weight to slow you down. And the Vento Ferox definitely won't hold you back. The upper is an innovative design using materials engineered to deliver a snug, supple and lightweight fit but one that's also incredibly durable. Excellent tear-resistance maintains off-road durability while excellent breathability keeps feet fresher during the heat of competition.BOA® Li2 Fit System x Fizik PowerstrapTo give a precise and comfortable fit, the Vento Ferox combines the precise fit of a BOA® Li2 Dial with the secure, foot-hugging comfort of Fizik's Powerstrap design.The Li2 dial features a composite over-mould design to give improved grip and input toque, making it easier than ever to tighten and loosen your shoes. With quick and easy micro-adjustment, fine-tuning the fit to your particular foot shape is now incredibly easy.With a lower profile than previous versions, the Li2 dial also marginally improves aerodynamics while also making it less vulnerable to being accidentally hit - ideal for rough trails and close competition.Meanwhile, the Powerstrap system features a wide, lightweight and reliable hook and loop strap system that, unlike a traditional strap, pulls together the two sides of the upper thanks to the ribbon wrapping around the foot. This provides even pressure across the whole foot and delivers an unrivalled level of riding comfort with minimal bulk and less complexity.Carbon OutsoleAchieving a 10 out of 10 on Fizik's stiffness scale, the UD carbon composite sole unit will ensure you surge ahead of the pack with maximum efficiency and ruthless accelerations. With your power going straight to the pedals all your hard training to get race fit isn't wasted.When you're off the bike, all-terrain traction is taken care of via the rubberized tread across the heel and to the outside of the cleat area. And for particularly muddy races, you can add toe studs to boost grip - perfect for the steep muddy runs of cyclocross in winter.Features:Innovative tear-resistant upperFlexible, lightweight and breathable upperUD Carbon Outsole - Rated 10/10 on the Fizik stiffness scaleBOA® Li2 single dial Fit System and Fizik Powerstrap provide a secure, precise fitRubberized tread patternRemovable toe studs2-bolt cleat compatible (cleats not supplied)Buy Fizik Footwear from Chain Reaction Cycles, the World's Largest Online Bike Store.
