SIDI Rex Boots The Rex Boot from SIDI, constructed of Technomicro base material and thoroughly tested by SIDI’s own Moto-GP riders, is a highly technical, class-leading sport boot. Equipped with SIDI’s exclusive Tecno-3 Push Closure System, the Rex Boots eliminate traditional buckles and laces. Instead, the boots are secured by three separate and adjustable steel cable closures. Each closure is comprised of a circular dial and push button that allows the dial’s arm to be lifted and rotated for increased closing pressure. Limiting lateral movements, the Rex Boots feature a single ankle support brace that combines with the internal and external ankle joint for additional support. Additionally, the bottom of the ankle brace is equipped with air vents which can be operated by an aerodynamic button. The Rex’s toe slider also features an optional vent operated by a sliding mechanism located towards the front of the boot. Sizing: Fits roughly a half size small from what the Sidi size chart indicates Pat from the video requires a Sidi 45 / US 11 to fit his US 10.5 foot Even with the proper shoe size, boots are extremely tough to get on and off Moderately wide footbed Features: The top of the line race boot from Sidi Race / track level protection and a full host of replaceable parts Uses a hybrid inner bootie system: The bottom of the bootie is one piece The top is split into an inner core and outer section Not a true inner bootie system as used by other brands About 5/10 stiffness and a moderately wide footbed for a track boot Technomicro base material SIDI’s exclusive Tecno-3 Push Closure System Elastic panels in the front and rear of the boot in flex areas for maximum comfort A single ankle support brace, nylon material infused with fiberglass fibers, joins the internal and external ankle joint for more support The exterior ankle support brace is equipped with air vents Small ventilation slots at the center of the support brace Nylon inner sole with removable arch support pad Double stitched in all high stress areas Fully encapsulated heel cup Lined with anti-abrasion Cambrelle in the foot area for comfort Perforated Teflon treated nylon lining Toe slider comprised of nylon reinforced with fiberglass and fitted with an air intake and an innovative alloy insert Dual compound sole DuPont polymer toe shift pad CE certified to EN13634:2017
