It's not often that feet get all the glory — which is why the Darn Tough Women's Function X is loaded with details that make them fit and feel the best. Strategic cushioning and thinner, more breathable panels on top of the foot reduce uncomfortable bunching and pressure, while a shin pad protects against boot pressure on the hunt for the next powder stash. The payoff: superior grip, better tech, and more control. Merino wool handles the moisture, and the unconditional lifetime guarantee handles the rest. Knit in Vermont.
