I've got a pair of the Darn Tough Nordic socks (http://www.backcountry.com/outdoorgear/Darn-Tough-Merino-Wool-Nordic-Boot-Ultra-Light-Ski-Sock/DRN0003M.html) and these look pretty similar. But I'm wondering if these are ok for nordic skiing? Sometimes, I like to have a longer sock on.
Nordic skiing in these should be no problem at all.
