It redefines the notion. Solidity underfoot is its defining trait. Ice? Bring it. The IQ binding interface—a seamless, powerful meld of ski and binding—transmits the merest twitch to the edge. (So be ready.) And that strong, shapely tail slingshots you across the fall line. “An absolute blast,” said Morgan.
