The Professional Oil is a stylish closed back clog with a slip resistant polyurethane outsole, an anatomically shaped footbed and a rocker bottom. This collection is designed specifically around the foundation of the sole, creating a subtle rocking motion that actually propels you forward while taking pressure off each step. This movement reduces the strain on your lower back and legs, so you can live a lifestyle that allows you to feel good-all the way down to your toes. Heel Height: 2" Fit: This style tends to run small. For an accurate fit we recommend purchasing a 1/2 size larger than you typically purchase. For example, if you normally purchase a size 7, we recommend purchasing a size 7 1/2. Outsole: Polyurethane Upper: New Oiled Leather
