Alpinestars SMX 1 Vented Black Shadow Boots Review http://www.revzilla.com/motorcycle/al... For those looking to utilize a low profile, moto-functional boot with refreshed style, the S-MX 1 Black Shadow Boots are a great option. With an upper constructed of lightweight microfiber and breathable mesh inserts with perforated side panels, the elements of comfort that were paramount in its design can be seen (and felt!) throughout. At the same time, proper moto protection has not been sacrificed as it will come with a reinforced toebox, external TPU protection on the outer ankle, and an external TPU shift pad, slider, and heel counter... all of which is wrapped up in the new Black Shadow colorway fresh out of the Alpinestars design labs.
