Woolrich Red & Black Wool Check Plaid Buffalo Mule Clogs Size 7. Woolrich classic featuring wool upper with studded detail around the edges, 5” wood heel, 1” wood platform, lightly padded black leather insole, natural gum soles. Fabulous shoes! Gentle use worn once, excellent preowned condition aside from some light smudges on the heels—for which I will provide you with super fine sandpaper to remove; works like a charm.
