The Alpinestars SMX Plus V2 Gore-Tex motorcycle Boot is a highly protective CE approved sports boot with Alpinestars' unique Multi-Link Control system for advanced external protection and support for ankle articulation, limiting hyper-torsion, hyper-extension and hyper-flexion as well as providing Achilles and ankle impact protection. These also feature contoured high modulus shin plate protectors, dual density TPU replaceable toe sliders with screw-in assembly and TPU heel protectors to dissipate and absorb shocks and allow sliding during an accident. Along with this high level of protection, the SMX Plus V2 boots also have a Gore-Tex waterproof and breathable membrane to keep you comfortable (and dry!) in all conditions. These are made from ultra-lightweight yet durable advanced microfibre and feature Alpinestars Lace-Lock system constructed from an advanced polymer resin to guarantee quick, precise and secure closure. The front flex area is constructed with a soft microfibre for natural forward and back movement for a great ride without compromising on protection. Flexible accordion microfibre on the Achilles gives enhanced natural suppleness and strategically positioned ventilation area in heel and shin TPU provides enhanced breathability and optimum airflow. A stretch accordion panel is at the entry/exit of the boot for a great fit and ease of entry/exit plus a lateral micro adjustable ratchet top closure system is easy to use and secure. These are highly comfortable thanks to the Alpinestars anatomical and replaceable countered EVA footbed which gives arch support and forefoot pedal feeling. The sole is made from evenly textured rubber and is highly durable for great grip. This also comes with inner instep speed lacing closure and unique lateral zip for a precise and secure fit and this has a hook and loop tab locks the zip pull closed, keeping it flat and safe.
