Sock Geek Says:

This aptly named sock is barely there and seemingly light as air, yet manages to keep moisture at bay and blisters away. Great second skin fitted feel. Moderate under foot cushioning with no bulk. Reverse stitch toe reduces the possibility of abrasion.

Note:  White is the only sock available in large and XL sizes.
