The Alpinestars Supertech R are long racing boots with TPU features and micro-fibre panels.

This racing boot upper is constructed using microfibre with a dedicated laser perforation zone that provides optimum breathability and abrasion resistance while also delivering high levels of flexibility. The sole is made using a lightweight rubber which provides excellent grip on pegs. Furthermore; the bio-mechanical inner bootie is constructed from a 3D mesh material for a greater structure which improves rider comfort. The rear bellow is constructed in stretch microfibre for improved natural front and back movement; as well as this; thetop gaiter ismade in a microfibre material with TPU over injection for enhanced prehensility. This boot also has a hook and loop closure that secures the puller zip and remains in position.

These boots are equipped with a replaceable co-injected TPU toe slider with a screw system that protects the toe area against abrasion resistance. The heel plate slider design offers increased sliding performance and protection in the case of an impact. Another characteristic of the Supertech is a synthetic microfibre panel on the side to help against abrasion as well as the TPU shifter which improves protection on the lower medial side.
