What Our Gearhead(R) Experts Are Saying: "I wear these for everything-hiking, gym days, even running errands. They're light, breathable, and that deep heel pocket keeps them locked in place. They don't slide down or bunch up, and the cushioning hits all the right spots. Seriously, the most versatile sock I own." We live for days that flow from trails to town, and the FITS Go With The Flow Crew Light Sock keeps us moving in comfort no matter what's on the agenda. Modeled after FITS' most popular Original Fit style, this versatile sock is built for hiking, training, biking, climbing, and whatever else the day brings. Crafted from fine-gauge merino wool, it regulates temperature, wicks moisture, and resists odor-keeping us dry and comfortable through high-output movement or slow strolls alike. With FITS' patented Whole Foot Comfort design, including a Free Range Toe Box and Deep Heel Pocket, the fit is dialed, natural, and friction-free. Light cushion zones in the heel, toe, and arch add just the right amount of support without bulk, and the Upright Compression keeps the sock snug and secure all day long.
