Aero Timber Top Shearling 8" Side Zip Clay Brown Stock Sole (as pictured): F1Back then, we made them with rubber and a lace up leather upper. We kept the classic look but swapped the rubber for an AeroForm shell made with polyurethane. This provides more flexibility and will keep feet warmer because the polyurethane wont transfer cold to your feet like rubber can. The inside is smooth and seamless, adding to the overall comfortable fit and feel. AeroForm Technology, making a classic fit for the 21st century. Style: 667211
