New with Box. Size: 42 ( 11 1/2 12 ) The Professional clog is our iconic silhouette, our flagship style. It features a roomy reinforced toe box for protection and comfort. The contoured footbed adds support to the comfort features like a padded instep collar to feel good with virtually any foot. We set ourselves apart with a protective heel counter that allows the heel to move up and down freely while providing lateral stability, and the anti-fatigue rocker bottom, which is built to keep you moving forward.
