    Best Uses

    • Hiking With Smallboots

    These are great socks if your boots are a tad snug! I wore these all day on a grueling 11 mile hike to the top of Colorado's highest mountain! I thought I would have blisters by the end of the day, but like magic there were none! I also have thicker SmartWool socks and they are great too!

    Shopper  Why Did You Choose This?
    Edward F  These socks are my favorite. They have been durable and comfortable fitting my foot from toe to calf snuggly. They breathe well and don't smell. So I wanted to share them with my wife. The price was good from Sunnyside.
