The Alpinestars SMX-6 V3 Vented Boots are track- and street-focused motorcycle riding boots designed for riders who demand dependable protection, precise control, and all-day comfort. This black, silver, and red model is sized US 7.5 / EU 41 and features race-derived protection technology in a streamlined design that works comfortably under riding pants. Manufacturer Alpinestars and vendor part number 2223225-199-41 identify this specific configuration.
The advanced microfiber upper combines flexibility, abrasion resistance, and durability with laser-perforated sections for improved airflow. Air vents in the heel counter and shin plate, breathable mesh inserts, and perforated padding throughout the boot help manage heat and moisture during short commutes or extended rides. An ergonomic last streamlines the forefoot for improved control on motorcycle foot controls, while the elastic front gaiter and anatomical shape provide a secure, comfortable fit.
Protection is provided by a TPU lateral ankle brace, race-derived TPU shin plate, internal toe box reinforcement, Achilles support, and impact-resistant ankle protection. The ankle brace system supports the area between the upper calf, shin, and ankle while allowing natural articulation. Textile and soft TPU flex zones promote forward and backward movement without compromising coverage. A dedicated TPU shifter zone protects the lower medial side, and the Alpinestars Lace-Lock System delivers quick, precise closure. The medial side entry uses an elastic-mounted zipper with a wide hook-and-loop closure for a secure fit.
A removable dual-compound EVA footbed with Lycra covering, an internal shank reinforcement, and a lightweight rubber sole support comfort, arch stability, and grip on the motorcycle. The SMX-6 V3 Vented Boots combine protective construction, ventilation, flexibility, and rider-focused ergonomics for performance riding on the track or street.
