Based on the most popular Endurance training sock Darn Tough knits, the Spartan ¼ brings just a bit more grit and the spirit of competition. Flex zones deliver comfort when it’s time to Spartan Up, and Merino Wool – if you didn’t know – takes you all the way through.
Received the shipment very quickly. Love the socks. Thank you!
I bought two pairs, but I wish I'd bought 10. Seriously, these are the only socks I ever want to wear again. They're super warm on cold runs, they don't move around and cause friction, and are cushioned in all the right spots. Best running socks ever. Best all-around socks ever.
A terrific product!
