Sidi has announced its new motocross and off-road boot for 2020, the Atojo. It is designed to be light, sleek, and give the rider excellent bike control. Nine-time MXGP world champion Antonio Cairoli, two-time MX2 world champion Jorge Prado, and longtime MXGP racer Alessandro Lupino worked with Sidi’s technicians to finalize every detail on the Atojo. These riders were so essential to the development of the boot that Sidi named the boot in recognition of them. “Atojo” stands for “A” (Alessandro Lupino), “To” (Tony Cairoli), and “Jo” (Jorge Prado).

When designing the Atojo, Sidi and their riders wanted to create a boot that was lighter in the upper portion but still offered ankle protection and replaceable parts. The Atojo has a dual ankle hinge, with one hinge above the ankle and one below. It has ankle support bracing inside the boot that is designed to prevent hyperextension of the ankle, instep, and Achilles tendon. Three hyperextension systems are built into the boot including one with a replaceable insert on the front of the boot that is designed to allow a specific amount of tibia movement and freezes if bending is excessive. Rubber inserts along the suede and plastic inner shin help provide grip on the bike. The sole is replaceable via four bolts. The Atojo will be available in March 2020 and retail for $599.99.

Sidi Atojo SRS Technical Data

“Atojo” stands for “A” (Alessandro Lupino), “To” (Tony Cairoli), and “Jo” (Jorge Prado). According to Sidi, the three riders played a significant role in the development of the boot.

• The Atojo SRS’ upper uses “Technomicro” microfiber panels equipped with high-impact plastic protection. The tongue and front and rear joints are padded with materials resistant to water and the absorption of sweat, dust, and mud.

• The boot’s toe area outer surface is entirely wrapped in high-impact plastic with a grip-enhancing surface.

• The Atojo SRS is equipped with a rigid and replaceable nylon insert for metatarsus protection, which protects the inside of the boot in case the rider’s foot slips off the peg.

• The Atojo SRS plastics have an all-new design. The high-impact plastic heel is shaped and specially molded to improve foot safety in case of torsional twists and is shaped to ensure comfort and stability.

• On the inner shin, the boot leg is built of protective suede with embossed rubber inserts which, in addition to providing good grip on the bike, protect the rider’s leg from engine heat. Rubber inserts for a smoother surface area, greater grip, and control are strategically located on the inside of the ankle.

• The high-impact plastic shin plate is anatomically shaped; its structure also extends under the upper to increase protection.

• The Atojo SRS uses a three-buckle closure system. Each buckle works independently of the other. The buckle, micrometric memory adjustment strap, and hook are user replaceable.

• The buckles have only one fixed point at the attachment screw, which ensures easy closing, allowing the boot to adapt to the leg of the rider and provide greater comfort.

• A spoiler has been added to the lower buckle to deflect debris away from the buckle.

• Cambrelle is used to line the foot contact surface. The polyamide structure of Cambrelle has a high resistance to abrasion and a great degree of moisture absorption, thus ensuring a rapid drying of the fabric and preventing the onset of mold. From the ankle to mid-calf, the Atojo is lined with a jersey-treated material with a Teflon fabric protector. The Teflon treatment prevents absorption of water and sweat.

• The malleolus area is protected by ergonomic padding with memory.

• Around the calf, there’s an elastic gaiter with an anti-heat protection panel/calf plate. The gaiter is closed with a Velcro flap to prevent the entry of rocks and dirt and features a wide adjustment.

• The ankle panel with the central strap is replaceable using four screws that connect it to the boot.

• The shin plate is anatomically shaped polyurethane and extends under the upper for extra protection.

Sidi Atojo SRS Hinge Systems

• The Atojo SRS has two flex points. The first hinge is positioned under the ankle, to reduce thickness and make the boot smoother on the inside and more aerodynamic overall. Ankle support bracing inside the boot allows for only a limited range of movement to prevent hyperextension of the ankle, of the instep, and of the back tendon. This technology gives the rider greater security.

• The second joint, above the ankle, works in sync with the lower hinge and is said to improve the flexibility of the boot, making the bending movement fluid without compromising rigidity and lateral protection.

• There are three anti-hyperextension systems for the foot. The first is located on the first hinge, the second on the back of the boot (the bootleg leans on the ankle avoiding extra bending backward), and the third is frontal and is made up of a system that, through a screw on replaceable insert, allows a specific tibia flexion range and freezes if bending is excessive.

• A bootleg in polyurethane connected to the ankle strap through the second hinge protects the back of the boot and is positioned between the upper and the lining.

• The design and technology of the SRS (Sole Replacement System) are patented by Sidi.

• The central part of the sole is made up of a rubber insert with a new interlocking Dovetail system and four screws for easy replacement.

• The sole base is slightly higher than the Crossfire 3 for greater engagement with the upper.

• The tip, with traction grooves, and heel are fixed for race-level use. An enduro lug sole is also available.

• The heel area has a fixed insert in soft polyurethane that is said to make the boot more stable and offer grip against the bike.
