Key Features

Unparalleled Flex Control

A breakthrough innovation for the Tech 10 is the introduction of Alpinestars patented Frontal Flex Frame. Combining with the dual front and rear blade connectors, the Frontal Flex Frame gives the Tech 10 a complete and seamless flexion control system, from the foot shell all the way up to the shin plate, offering high performance double motion control, preventing over-compression and hyper-extension, featuring:

Engineered frontal flexion control offered by a dual-density TPU connector system, uniting the lower buckle plate with the upper blade connector, buckle and shin protector. Engineered to 'float' freely between the lower and upper boot construction, the Frontal Flex Frame acts as a shock absorber by distributing energy across the boot frame while controlling forward and rearward flex, progressively releasing force which dampens and absorbs impact energies.
Asymmetrical, dual pivot arms on boot frame.
Ankle Control System - A unique feature of the Tech 10 is the ankle control system developed in the outer shell construction, allowing natural ankle movement, vertical compression control and improved impact protection.

Construction

Innovative, lightweight upper construction, the Tech 10 chassis combines advanced lightweight microfiber and impact and abrasion-resistant TPU shell.

Foot shell features five different compounds in a single lightweight piece to offer strength while maintaining flexibility and structural integrity. Foot shell incorporates heel and toe protection that is highly resistant to abrasion and impact and adds to the boot â„¢s overall durability. Foot shell also includes integrated shank for support and structural integrity.

Frontal protection features a dual closure system with an internal microfiber flap, plus hook and loop fasteners for a precise fit closure beneath the buckle giving greater, micro-adjustable, precision which is convenient to operate. Soft microfiber gaiter helps seal out excessive water and dirt entry.Poly-fabric lining with 3D open cell foam incorporates anti-slip suede in heel area, keeping the foot located inside the boot.
