EUC. Earthkeeper with anti-fatigue insole. Comfortable for all day wear. Great with jeans, leggings, skirts or really any look ! Leather with Nubuck (top grain brushed leather) at the heel, back strip and top buckle. They are a lovely camel color, and hit mid calf (on a 5’6” woman). The measurements are shown; note the heel height 1.25”. They both zip and lace. Fully tied and zipped at the point of complete closure circumference at the top is 13.25”. So they can be loosened a bit to widen or relax them more if needed. Minor scuffs as shown adds character, and no attempt was made to cover or polish out. Scotch guard applied when new; can reapply if desired. The 10W refers to the calf. The foot part is true to a regular 10. The insole is removable if you wish to use an insert or thinner style orthotic.
