Leather: The Leather clog features an unlined, one-piece oiled Nubuck Ecco® Leather tanned with Dri-Tan water savings technology. The leather upper can get wet and dries relatively quickly, however, the Nubuck leather can show natural marks more easily from dirt + water than the synthetic. The Nubuck leather also may have natural imperfections. Compared to the synthetic version the leather has a slightly longer break-in time until the upper forms to your foot, is slightly stiffer, and it will also age / wear in more gracefully and is extremely durable.
Synthetic: The synthetic upper features a Clarino® microfiber upper lined with a comfy polyester spacer mesh. The synthetic upper can get wet and will dry relatively quickly, and the spacer mesh lining can act as a vapor barrier similar to an athletic shoe. Compared to the leather version the synthetic has less break in time, is more flexible, will not stain as easily, yet it will not age / wear in as gracefully and will develop more flex creases.
