Here's the top-performing wide-fit boot in the category. Even with a generous fit, the SX puts a ski on edge and ranges confidently all over the hill. Its flex is right on target and comfortable against the shin. It's solid on edge and quick in transitions. It rips in all turns, snow conditions, and terrain. It's not the easiest boot to get on, but testers said that's a fair trade-off for the performance. Eastman: "Zing! Snaps into performance mode right out of the gate. Flex is made for dynamic skiing."
