The Vierzonord is the perfect neoprene boot for everyday country life. Famed for being the original rubber wellington boot to feature an adjustable, waterproof gusset, the Vierzonord also boasts an insulating neoprene lining that will keep you warm and comfortable all day. Please note: Neoprene has wonderful insulation properties, but it is not a breathable material. If you wear neoprene-lined boots in warm temperatures, or if your feet heat up while you are wearing them, you may perspire.
