Whether we're stretching our legs at a rest stop off the interstate or huffing and puffing up the first big hill on our hike, the Darn Tough Vanna Grizzle Boot Midweight Sock shows off a little bit of style while keeping our feet snug in our trusty boots. The durable nylon and Merino blend is made with a hint of stretch to make for quick on-offs, and the targeted cushioning provides plush comfort for long days on our feet.
