The lightweight Burton Women's Merino Phase Socks are a blend of the most advanced features and materials known to sock science. These include, but are not limited to super insulating Merino Wool, stretchy nylon, and climate controlling NanoGLIDE™. DRYRIDE Venting Toe Panels are like the dual overhead cams of socks, wicking away heat-robbing sweat with turbo-charged efficiency. Going one step further, the Merino Phase is also engineered with anatomical padding and an ergonomic MotionFit, which our sources tell us, will allow you to carve quicker, land flatter, ollie higher, and hike higher.
