This Alpinestars SMX-6 V2 Gore-Tex Boots review looks at a waterproof road and race boot with microfibre construction and lateral ankle support. Front and rear flex zones, a removable footbed and a broad upper closure make a full riding-position fitting worthwhile.

Ankle support and side-entry adjustment
The lateral TPU brace links the calf, shin and ankle areas, while the inner ankle has dual-density protection. Assess the position of these components with the boot fastened and your knee bent. The medial entry zip is elastically mounted and works with a wide hook-and-loop closure; both should close without forcing the upper around your leg or disturbing the liner.
Bellows and accordion sections provide flex at the front, instep and Achilles area. A shank reinforces the insole, with a removable EVA/Lycra footbed above it. Try the complete pair with your normal socks and check heel retention as you move between the gear lever and footrest. Gore-Tex is the listed waterproof layer, while the protective structure incorporates vents. Those details describe the equipment, not a measured temperature or comfort result for a particular ride.
Protection and construction
The specification lists protection at the shin and ankle. Check that these areas sit correctly when you adopt your riding position.
