K2's Supermodel line includes the 80 mm-waisted SuperGlide, dubbed "reliable and surprisingly agile in bumps," according to Sutton. K2's Bioflex 2 core combines strong aspen wood underfoot with lightweight paulownia in the tip and tail. This works in concert with Hybritech Sidewalls, a combo of sidewall and cap construction, reducing swing weight while increasing stability and edge hold. An elevated tip helps the ski initiate turns easily as well as adding some soft snow performance. "It's not powerful, but it's smooth and stable everywhere," said Alder.
