Smartwool PhD Ski Medium uses a merino wool and nylon blend with the Indestructawool reinforcement at the shin area where ski boot buckle tongue pressure creates wear. The zoned cushioning places medium padding at the shin and heel while keeping the forefoot thin for better boot fit and power transmission to the ski edge. The full over-the-calf height keeps the sock from sliding during skiing.
