The Sonja Cabrio is our open back version of our classic black professional clog. Great for those long shifts on your feet, and helps support on long days. The open-back slide features a black cabrio leather upper with a padded instep and an anatomically correct footbed. The cabrio leather moves with you and ages beautifully with time. The polyurethane outsole features a rocker bottom. This style is approved by the APMA and part of our Professional Collection.
