The Alpinestars SMX-S motorcycle boots are designed for riders seeking dependable protection, comfort, and performance during street and sport riding. This black riding boot features a durable microfiber upper that provides flexibility while supporting long-lasting wear. A waterproof and breathable membrane helps manage changing weather conditions, keeping the interior more comfortable during wet or variable riding conditions. The boot is sized for US 13.5 / EU 49 and is identified by Alpinestars manufacturer and vendor part number 224351710049.
Protection is built into the SMX-S through an ergonomically shaped TPU shin plate, lateral TPR-injected ankle support, and dual-density TPU ankle protectors positioned beneath the upper on both sides. Internal toe protection adds durability and helps maintain a secure, responsive feel while riding. The integrated bi-injected TPU slider uses a replaceable, no-screw design for convenient servicing. A textured TPU shift pad protects the boot and improves grip during gear changes.
The medial-side entry system combines an elastic-mounted zipper with a wide hook-and-loop closure for a secure, adaptable fit. Its large opening promotes easier entry and removal, while the dual-compound removable anatomical footbed uses EVA and Lycra to provide cushioning, support, and comfort. A compound rubber sole delivers reliable grip, water dispersion, durability, and improved foot control. With its combination of weather protection, protective components, and rider-focused construction, the Alpinestars SMX-S is a practical choice for street and sport motorcycle applications.
