Smartwool Pika Puff Sock. Extraordinary comfort, exceptional fit, lasting quality.
The stylish design, ultra light cushioning, and its supportive arch brace make this sock the one to buy for the cold weather. WOW technology, wool-on-wool, strengthens the socks for added durability. And since WOW reduces nylon content these long-lasting socks move moisture better and control odor and temperature more effectively.
