The original and the best. People expect a lot from a chore boot, and we always aim to exceed their expectations. In addition to the tough performance you expect from muck, now we have added a gusset construction to our iconic chore boot, which has helped workers stay dry and comfortable for more than a decade. Rugged and built to last, the chore xf delivers the same performance and protection as the original with up to 5 extra inches of calf accommodation for optimal fit and comfort.
