The Alpinestars SPX Boa Drystar Boots are sport touring boots in Black/Dark Grey, designed for all-weather riding. A waterproof, breathable Drystar membrane is built in. The rubber sole has a special compound for grip and shock absorption.
The upper combines microfibre, knitted mesh, and Lycra co-injected with TPU. The front bellow is Lycra co-injected with soft TPU. The rear calf panel is textile. The lining is 3D mesh, with micro suede on the heel to keep the foot from sliding.
A BOA Speed Lace System on the lateral side closes the boot quickly and precisely. An adjustable hook-and-loop closure on the shin plate has a TPU 3D print for grip. Protection includes a TPU shift pad, TPU sliders on the lateral toe box and calf, a TPU heel counter, dual-density ankle protectors, and internal shin reinforcement.
