* All measurements are in inches. Measure bare foot from heel to longest toe.
* Sock fit works with low‑cut, crew, mid‑calf and over‑the‑cuff styles.
* If between shoe sizes, choose the larger sock size for better comfort with thick boots.
* Merino wool will stretch with wear; compression varies by cushion weight: light, mid, heavy cushion.
In honor of the Civilian Conservation Corps youth who helped shape our modern National Park System, we made the Northwoods hiking sock to work hard. But hard labor is no match for their soft, snug fit. Sure, they'll crush trails like a pound of dynamite, but with details like breathable cushioning and low-profile, slouch-free 1x1 ribbing, the only grunt you'll make is when the wildlife tries to steal these socks.
Machine wash in cold water on gentle cycle with socks inside-out. Do not bleach. Tumble dry on low or hang dry. Do not dry clean. You can learn more about how to wash merino wool socks here.
