Yes. The knit is light, but the high-stress areas (heel, toe, ball of foot) are reinforced for repetitive movement.How does the ventilation actually work? Open mesh channels are knit into the top of the sock, which lets heat and moisture escape while the structured zones hold the sock in place.Are they sold as a pair? Yes, one pair per box.Will they keep my feet warm in cold weather? No — the TA4 is intentionally cool. For colder conditions, the FS4 Merino Wool sock is a better choice.
