Loading... Please wait...Fishing with cold feet is no fun. We get asked all the time how to avoid cold feet and one of the ways is to be wearing the right socks. We have had plenty of February days on frigid winter steelhead streams to tell you that the Simms ExStream Wading Socks are excellent. They are 85% Merino wool and keep your feet warm and also dry. They are durable and comfortable and will make you a fan. For even more warmth and moisture wicking, consider also using Simms Waderwick Liner Sock underneath against your skin.
