Get ready to phase out all your old socks, because you've just met your new go-to foot glove for all things on the mountain. There's so much technology packed into this sock you'd think it was a nanocomputer designed by NASA. Check it: this thing has Sock Lock Reinforcements to keep your foot from sliding and reduce abrasion, merino wool to regulate temperature and reduce foot funk, a Chafe-Free Link Toe Seam to further reduce abrasion and blisters, DRYRIDE Ultrawick Vents to keep things cool all day, Ergonomic MotionFit to fit better than spandex on Richard Simmons, plus a Quick-Drying Footbed and a Stay High Comfort Band. Don't call it a comeback, but this sock is what's up.
