Sizing depends largely on what styles of footwear you're interested in.
For our women's Classic Collection, we would recommend ordering down in size. These styles tend to run large, and the sheepskin suede does stretch with wear. For the Classic Collection, we would recommend ordering a full size down if a whole size, or a half-size down if in between sizes.
However, our fashion boots and our rain and weather styles have a tendency to run more true to size, and are often available in half sizes. For these styles, we would usually recommend ordering your regular size. Specific fit information may also be listed on the product page.
