What Our Gearhead(R) Experts Are Saying:"I wore the Vinst Sock 2-Pack on a cold trail run last week and my feet stayed warm the entire way down. The reinforced heel and toe held up fine even after a muddy, rocky descent."Cold toes end a run faster than tired legs ever will, and the Kari Traa Vinst Sock 2-Pack takes that excuse off the table. Merino wool blended with just enough synthetic fiber holds warmth through a full loop in freezing temps, while full sole cushioning and arch support keep the miles comfortable well past the halfway point. Reinforced heels and toes push back against the wear that ends most socks early, and ribbed cuffs keep everything in place without cutting off circulation. Two pairs land in one order, which means one pair working while the other dries out from yesterday's effort.
