Endurance athletes log hundreds of miles before they put their gear to the true test during a race. For runners, socks and sneakers are the most important parts of in their kits — a blister at mile 10 turns into a nightmare at mile 50. Smartwool teamed up with Rob Krar, an endurance athlete who won the Leadville 100 last year, to create the PhD Pro Endurance Print crew socks. Inspired by Krar, these socks are built for runners who log 100 miles, so that they work for any number of distances.
In 2018, Krar won the Leadville 100 for the second time. It’s one of the most intense trail races in the country due to the changes in elevation from 9,200 to 12,600. To survive each mile, Krar needs proper gear — including these socks. The Smartwool PhD Pro Endurance Print crew socks come with Shred Shield technology — a proprietary technique Smartwool uses to eliminate the inevitable holey socks problem. Since ultra-runners spend a lot of time on their feet, pounding the ground, there’s extra cushioning in the sole and ankle for added support. Smartwool made sure to keep the socks breathable and seamless, using Indestructawool. It’s a patent-pending construction method that keeps wool together for much longer than previous iterations.
