Performance Crew Socks, Made in the USA

Driven to make an everyday sock that fits better, feels better, and keeps you comfortable mile after mile, we teamed up with Fitsok: a North Carolina–based brand that has changed what we can expect from the classic 3-pack. This time around, we’re offering a crew version, great for anyone who wears boots, wants extra warmth or skin protection, or simply prefers a taller sock. Featuring a soft, comfortable blend of American-dyed merino wool and nylon, this sock is technical enough for hiking, biking, running, and other active pursuits, with a clean aesthetic that’s well suited for daily wear.

Note: The Massdrop x Fitsok Merino Crew Socks will launch and end each day to collect purchases. Items will ship within 2 to 3 business days. At checkout, you’ll have your choice between the all-black 3-pack, the forest green/orange 3-pack, the light gray/navy blue 3-pack, the gray/purple 3-pack or the mixed color 3-pack, which contains forest green/orange, gray/purple, and light gray/navy blue. Available sizes range from unisex S to XXL.

Materials & Construction

Merino wool is naturally thermoregulating, which means it keeps you warm in cold weather and cool in warm weather, and prevents overheating and clamminess by absorbing and releasing vapor. It’s also naturally antibacterial and odor-resistant, so you can stretch an extra day out of your pair when you need to. The addition of nylon takes the durability up a notch, and the touch of Lycra adds just enough stretch. Light cushioning under the heel and toe areas provide support where you need it, while lighter mesh weave on the top improves breathability and fit. Plus, the arch compression creates a secure fit and improves comfort. The Massdrop logo is subtly placed on the interior of the shin, so you can catch a glimpse of it every time you pull your socks up.
