The Light Hiker Quarter sits above the ankle and based on our most popular ORIGINAL FIT style. A balanced base layer with a lightweight profile, strategically-placed LIGHT cushioning zones, and the 'custom-fit-feel&&';; of our patented 'Y-Line&&';; knitting structures. While we call it a light hiker, it&&';;s remarkably versatile, comfortable, and loved for all sorts of wearing occasions. Hike, Run, Walk, Train, Climb, Bike, All Day Patented Whole Foot Comfort Engineering 144N Knit with a fine gauge merino wool for temperature regulation and ultimate softness.

Patented Deep Heel Pocket wraps the foot, holds in place, and prevents blisters. Strategic cushion zones in the heel, toe and arch. Best. Sock. Ever. In 2010 we set out to make the best fitting sock that could be made. And we did.

Whole Foot Comfort begins with premium fabric. That&&';;s why we ground our knits with a higher quality 18.5-23.5 micron 'fine-gauge&&';; merino wool. The kind typically used in luxury formal wear. This gives FITS a distinctly different, and superbly soft, feel unlike any other performance sock. Because no other sock is made like FITS.
