Skateboarding not only empowered man to surmount hazardous half pipes and treacherous sidewalks, it also inspired a whole new vocabulary of colourful terms such as "thrashed," "stoked," and "fiscally responsible."

Xtreme Adrenaline, a rider-owned-and-operated mecca for skateboarding, snowboarding, and longboarding merchandise, purveys an array of boards, apparel, and accessories made by the industry's top brands. Shoppers can don board-ready threads such as an Enjoi fuzzy panda hoodie ($69.99) or can give feet better on-the-ramp traction than their current patent-leather mary janes do with a pair of high-top sneakers ($79.99) from Element Omahigh. Xtreme lets shoppers customize their rides with an extensive selection of board components and accessories and offers complete boards, including the Darkstar cross skateboard, which sets a durable, seven-ply rock-maple board atop ABEC 5 precision-bearing-filled 52-milimetre wheels ($99.99). Riders of other persuasions or those looking for a creative way to get to the grocery store can peruse the shop’s longboards ($200+) and snowboards ($300+).
