A big contributor to getting cold feet while wading is wearing two pairs of thick, bulky socks that make your boots fit too tight and reduce blood circulation. These Liner Socks take up very little room and are perfect under Simms Exstream Wading Socks for cold situations. Made of 93% CoolMax Polyester, 6% Nylon, 1% Spandex. Wicks moisture quickly and uses X-Static® nylon to eliminate foot odor. Made in USA.
