Brand new for Spring 2018, the Alpinestars Limited Edition Schwantz Supertech R Boots were designed to celebrate the 25th anniversary of Kevin Schwantz's World Championship title. We have very limited supply of these boots with less than a handful of each size (42-46 only) Made of microfiber and synthetic leather, the Supertech R is both light and durable. A new front flex area made up of thermoplastic polyurethane (TPU) and mesh provides a more breathable and comfortable fit. This new construction is more abrasion resistant than the original version. The sole of the boot is made out of lightweight rubber that is flexible for when the rider changes positions. Additionally, the boot contains a replaceable, co-injected TPU/aluminum toe slider for added toe protection. The protective polymer heel plate slider is also replaceable. The Supertech R has accordion microfiber stretch in both the Achilles and the top of the boot, making it easy to put on and take off. The boot is equipped with both a TPU zipper and a Velcro tab to ensure the boot stays closed during use. It also features a micro-adjustable ratchet top closure for a safe and precise fit. A completely removable inner ankle brace provides protection to the side and back of the foot. 3D mesh material wicks moisture, keeping feet cool and dry. These boots are CE certified to EN 13634:2010 standards.
