Dansko’s legendary Professional clog launched a comfort generation. Loved by millions, this iconic style offers unbeatable all-day comfort and support. AMPA accepted. This clog should fit snugly at the instep, with room for toes to wiggle freely, and loosely in the back so that the heel moves up and down as you walk (a pinkie finger might fit between your heel and the clog). 1/2 sizes should size up to next size.
