Alpinestars' fitting advice is to try boots on with the socks you ride in, fasten everything, then walk, bend and sit on a bike before deciding. They also note that a new boot is stiff until it breaks in.
Care Instructions
Alpinestars' guidance for their road footwear: clean dirty boots under running water with a sponge, and do not pressure-wash them. Do not use strong cleaning agents or solvents, which can weaken the materials and damage the colour and finish of the plastic parts. Wipe off surface water with a cloth and lay the boots on their sides to dry naturally, with the inner bootie taken out and dried separately. Do not dry them next to a fire or a radiator. Store them fastened, in their box, somewhere well ventilated rather than in a cellar or a plastic bag. Check that the sole still has tread and the fasteners still work, and inspect the boots thoroughly after a crash. Alpinestars say a boot that can no longer be fastened properly, or has holes or tears, must be replaced, and must not be modified or repaired by the user.

Description:Alpinestars Supertech R Boots – Black/White
Product Overview
The Supertech R is what Alpinestars call their definitive racing boot. They describe this version as a rework of almost every component: the front flex area, the rear bellow, the top gaiter, the shifter panel, the shin plate, the shin slider and the inner bootie, with the changes coming from feedback out of their own racing programs.
The boot is built in two parts. An outer chassis in technical microfiber carries the shin plate, sliders and closures, and a separate bio-mechanical inner bootie in 3D mesh sits inside it with its own toe reinforcement and ankle padding. The toe slider, shin slider and heel plate slider all screw on and can be replaced, so the parts that touch the ground in a crash can be changed without retiring the boot.
This is the solid version. Alpinestars also build the Supertech R Vented, with a laser-perforated upper and ventilation channels through the front flex area for hot weather.
