The Alpinestars SP-1 boots are a very versatile motorbike boots that combine the comfort and sportivity of urban footwear with the protection of specific motorbike boots, being the solution for those who want a protective boot for a daily use.
Materials and protection
Ther main material is microfibre, mixed with other light materials, according to offer the maximum protection to the abrasion and wear and mantaining the comfort for a daily use. For this purpose, there are accordion areas of the microfibre to allow the feet movements. We find also slides on the external side of the boot, made with thermoplastic rubber (TPR) and a external protector on the ankles area, made with the same material.
On the instep area there is a reinforcement made with thermoplastic poliuretane (TPU) that provides protection and optimal touch when we change the gear on the bike. On the heel there is a TPU protector that provides rigidity on that area.
Interiors and closures
The interior textile is microperforated and has been designed to offer breathability to our feet, but also provides other details, like a special textil in the heel's area that guarantees the grip of the foot inside the boot, avoiding the displacement. According to provide an optimal touch, there are padded areas on the leg of the boot and the instep areas.
Between the inside layers, there is a double density protector on the ankle's area, and a toecap reinforcement whoch offer additional protection to the boot. The kevlar cords is the closure system used on these boots and the adjustment mechanism is the same that we find on the brand's most sportive boots: the Supertech R boots. Finally, a Velcros' strap adjusts our feet to the boots.
Sole and other features
The Alpinestars SP-1 have an anatomical insole made with the mixing of lycra and EVA foam. Below, there is a material (polyamid) that provides ergonomy and protection to our feet.
The sole is made with an exclusive rubber compound that offers traction and grip on the stirrups. This sole has two levels for an optimal grip and its grooves offer an excellent water drainage and evacuation.
As a detail, we find a reflective insert placed in the back of the boot, that optimizes the boot's visibility.
Summarising, the Alpinestars SP-1 boots are more than urban motorbike footwear, because its protection levels are higher, (rigidity on the most demanded areas and even ankle protection) without losing the sportivity and comfort we need for a daily footwear, getting that mixing between urban boots and the protection needed for those who ride a scooter or motorbike every day.
