The Atojo SR Hinge System 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 hyper-extension of the ankle, the instep and the Achilles.
The second flex point, above the ankle, works in sync with the lower hinge and improves the flexibility of the boot. Bending in the boot is a fluid movement without compromising rigidity and lateral protection.
Three anti-hyperextension systems are in place with the Atojo SRS Boots
Aside from the innovative SR Hinge System, a second feature on the back of the boot actively limits excessive rearward flex
The third anti-hyperextension system is frontal and allows only a specific range of tibia flexion. The system uses a replaceable guide that is anchored to the hard PU toe box to freeze the foot if excessive movement is reached.
TECHNOMICRO Upper with High Impact Reinforcement:
The full boot upper is constructed of TECHNOMICRO synthetic suede with high impact PU plastic reinforcement
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 bacteria. From the ankle to mid-calf the Atojo SRS Boots are 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 an ergonomic padding with memory
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.
The ankle panel with the central strap is replaceable using 4 screws that connect it to the boot
3 Buckle Closure:
Each buckle works independently of the others. 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 to provide greater comfort.
All buckles move independently of each other and have just one fixed point (by a screw) which allows easy closure and the buckles can adapt to the rider’s position as they pivot on the mounting screw as the rider changes position on the bike
A spoiler has been added to the lower buckle to deflect debris away from the buckle
Micrometric memory adjustment straps and hooks are replaceable
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.
Dovetail SRS Sole System:
The Dovetail SR (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.
Toe and heel areas on the Dovetail SRS sole are now a permanent part
Removable arch support
The sole base, or boat, features a more aggressive look and is slightly higher than the Crossfire 3 for greater engagement with the upper
An enduro lug sole is also available
Adjustable Calf System:
Sidi's exclusive double-adjustable calf plate system allows the rider to adjust the inner diameter of the calf. This system, along with longer upper straps, allows the Atojo Boots to accommodate riders with larger calves much easier. The inner plate is made of two different materials: a rigid one to support the boot and a heat resistant one to protect the rider's leg from exhaust heat.
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
Sidi boots do not incorporate inner booties into their design, and for good reason. 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.
