The Alpinestars SP-2 Riding Shoes in black, size US 9 / EU 43, deliver low-cut sport riding performance with a focus on comfort, fit, protection, and durability. Manufactured by Alpinestars and identified by vendor part number 2511622-10-43, these motorcycle riding shoes are designed for riders who want responsive control on the bike without sacrificing walkability off the bike. The lightweight microfiber upper resists abrasion while providing flexibility, and the ergonomic boot shape accommodates a wide range of foot profiles.
Fit and Support: An innovative heel counter support system works with the anatomically angled strap closure to provide a secure, comfortable fit over the instep. The front hook-and-loop closure includes a TPR puller for easy adjustment, while durable aramidic fiber wires keep the strap system thin, lightweight, and reliable. A reverse zipper closure makes entry and removal convenient, and the removable anatomical footbed combines EVA foam and Lycra for supportive comfort. Internal mesh lining helps promote cooling airflow and moisture management.
Protection and Control: Alpinestars protective construction includes double-density ankle protectors beneath the upper, an external high-modulus TPU heel counter, lateral ankle reinforcement, internal toe protection, and a replaceable bi-injected TPU forefoot slider with an easy-screw replacement system. The sole incorporates the Alpinestars TPF, or Transversal Protection Frame, to help protect against transverse loads while preserving useful flex. A compound rubber sole with a grip-focused pattern improves traction, feel, water dispersion, and durability both on and off the motorcycle.
Flex zones at the instep, Achilles area, and rear heel support natural ankle movement and rider control. Thermowelded flex grooves help manage movement through the instep, medial, and rear sections, while the rear flex window also functions as an air intake for improved ventilation. An ergonomic TPU shift pad reinforces a high-wear control area. These Alpinestars SP-2 motorcycle riding shoes fit riders seeking a streamlined, protective shoe for street and sport riding applications.
