Sidi Atojo Srs Lead Grey/Black Mx Boots

ATOJOSRS43GB, ATOJOSRS44GB, ATOJOSRS45GB, ATOJOSRS46GB, ATOJOSRS47GB Sidi are once again revolutionizing the world of motocross boots. The name "Atojo" is an acronym that represents three of Sidi's world-dominating MX riders: "A” as in Alessandro Lupino, "TO” as in Tony Cairoli and "JO” as in Jorge Prado. This collaboration created an MX boot that balances protection, durability, comfort and lightweight - all while maximizing the rider's connection to the bike. The acclaimed SIDI cam lock buckles and straps, a wide calf opening and compatible interface with knee braces will find a fit for virtually every rider. The unique Atojo SR Hinge System makes Sidi's existing ankle protection system even better. The dovetail sole from Sidi's Crossfire 3 and replaceable buckles will keep this pair of MX boots performing for years of hard riding. Sole Replacement System (SRS): although hard wearing, the sole is easily replaceable if needed. Just 4 screws allows you to refresh your boots with a brand new Click Sole (sold separately) Atojo SR Hinge System: two flex points allow the ankle to move naturally but prevents hyper extension of the ankle and the Achilles Hyperextension Control: prevents excessive flexation rearwards, frontwards and protects the lower tibia from hyper-flexation TECHNOMICRO Upper with High Impact Reinforcement: the whole boot is constructed of synthetic suede with high impact PU plastic reinforcement Around the calf is an elastic gaiter with an anti-heat protection panel/calf plate. The gaiter is closed with a hook and loop flap to prevent the entry of rocks and dirt and features a wide adjustment. Crossfire 3 origin 3 Buckle Closure: replaceable and customisable All buckles move independently of each other and have just one fixed point (by a screw) Adjust the straps once and they will be at the same position for every ride after that. No more readjusting for every ride or mid-day during a ride The Dovetail SRS (Sole Replacement System) is designed and patented by Sidi. The central part of the sole is made up of a rubber insert with a new interlocking dovetail system with 4 screws for easy replacement. A deeper tread Enduro Click Sole is also available (sold separately) Adjustable Calf System: allows the rider to adjust the calf inner diameter to suit more people Malleolus external plastic guard with ergonomic closed cell foam padding internally to enhance protection of small foot bones Replaceable inner kick starter/foot peg nylon guard on the inside area of both boots Boot leg is fully assembled with screws, is stitch-free and entirely replaceable All bolt-on parts are replaceable Replaceable shin plate Non-Bootie Design: Booties make the design larger and cumbersome, add to the boot's thickness, which interferes with shifting. Inner booties retain body heat affecting the rider's performance and comfort. Replacement parts available. SIDI boots are a narrow fit and they recommend going up a size from what you would normally wear.
