Part of our Thermal Series, the Blundstone #584 Chelsea boot features premium leather that is specially water-resistant treated and tight-knit coated elastic with sealed elastic seams and thread to shield your feet from the elements. You can expect maximum comfort too with Thinsulate® insulation and Sheepswool lined footbeds for extra warmth. A durable boot that can truly stand-up to the cold. Please note: Blundstone leathers are kept as close to their natural state as possible and natural colour variations are to be expected. This can cause the leather to appear different from product images and develop unique character as it ages.
