The Ski Pro Sock from Point 6 has the same thickness throughout as the ultralight sock except on the shin and around the Achilles where there is extra padding. Point 6 uses a method they call compact wool design make the socks. The result is a tightly wound wool that does not fray and therefore is very durable.
We recommend this sock for skiers who use a Surefoot Custom ski boot and those with regular liners that fit snuggly.
