The Alpinestars SP-2 Riding Shoe in black, US 12.5 / EU 48, is a low-cut performance motorcycle shoe designed for riders who want dependable protection, comfort, and control on and off the bike. Manufacturer and vendor part number 2511622-10-48 identifies this model, which uses a lightweight microfiber upper reinforced with strategically positioned TPU protectors for abrasion resistance and durability.
Fitment: Designed for motorcycle riders seeking a secure, supportive fit with broad forefoot comfort and excellent control on the bike’s foot controls. The ergonomic shape accommodates a wide range of foot profiles, while the front hook-and-loop closure and anatomically angled strap provide quick, adjustable retention over the instep. A reverse zipper closure helps make entry and removal convenient, and the internal mesh lining promotes airflow and moisture management during extended rides.
The heel counter support system works with the strap closure to improve fit, structural integrity, and ankle support. A soft TPR insert and rear flex zone encourage natural ankle movement, while accordion flex panels at the instep and Achilles area enhance maneuverability. The rear flex bellow includes a ventilation window, and thermowelded flex grooves help regulate movement through the instep, medial, and rear sections of the shoe.
Protection comes from double-density ankle protectors, an external high-modulus TPU heel counter, internal toe reinforcement, and an integrated replaceable bi-injected TPU forefoot slider. The ergonomic TPU shift pad helps protect a high-wear area. Alpinestars TPF protection is integrated into the sole to help manage transverse loads, while the compound rubber sole provides grip, water dispersion, and durability. A removable anatomical footbed with EVA foam and Lycra supports all-day comfort.
