The Snap-on Tools N.O.S. boots, manufactured by Coastal Boot, utilize full-grain leather and mesh uppers. The leather provides strength and support where needed, and the mesh portion reduces overall weight and improves air circulation. The unique design is exclusive to Snap-on and includes a YKK zipper for easy on/off. The YKK zipper on the inside ankle is the same used in better known SWAT tactical boots. The polyurethane insole and outsoles are lightweight and provide comfort and stability for all-day use.
