"Full Description:\nBack 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 won’t 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.<br><br>\n\nFeatures:\n\u003cul>\n\u003cli>PULL TAB: A back leather pull tab makes it easy to slip into this boot.\u003c/li>\n\u003cli>Seamless interior for a comfortable fit\u003c/li>\n\u003cli>Comfort Zone: 0 to 70F\u003c/li>\n\u003cli>Shearling lining for superior insulation\u003c/li>\n\u003cli>Top zip closure for easy on and off\u003c/li>\n\u003cli>AeroForm shell for flexible, cold-resistant warmth\u003c/li>\n\u003cli>6-inch shaft height for ankle support\u003c/li>\n\u003cli>Polyurethane footbed for all-day comfort\u003c/li>\n\u003cli>AEROFORM SHELL BOTTOM: Made of polyurethane, our AeroForm Shell wraps the foot for cushioning comfort and waterproof protection.
