SMARTWOOL goes back to basics with its WALK LIGHT Crew Sock. Light cushioning under the foot offers additional impact absorption without too much bulk. Merino wool is a lightweight and breathable fabric that keeps you cool when things get hot. Minimal stitching around the toes avoids fabric bunching up, which leads to discomfort. The arch and ankle support help keep the sock in place. The waffle knit flex zones give you full mobility while retaining shape.
