You will never have to sacrifice comfort for performance when wearing UltraBoots from UltraSource. The comfortable, heavy duty polyurethane (PU) material lasts 3x longer than PVC and is also highly resistant to harmful acids, fats, and chemicals. Unlike other boots that stiffen in the cold, UltraBoots’ 3 molded flex points help retain elasticity and range of motion in extremely low temperatures. The 100% waterproof construction keeps feet warm and dry on the job. UltraBoots’ soles feature a unique design with numerous exit points that give the wearer better traction in wet environments. Though UltraBoots are used in a variety of industries, they are commonly used by food processors, cold storage workers, hunters, gardeners, fisherman, and other professions in which comfort and safety are crucial. Polyurethane is tough but also lightweight, which reduces fatigue throughout the day so you can tackle any job. For added comfort, UltraBoots’ plush ergonomic insoles provide both arch and back of foot support.Safety toe meets ASTM F2413 – 11 I/75 and C75.UltraSource Equipment and Operational SuppliesSince 1883, UltraSource has served the processing and packaging equipment needs of thousands of companies worldwide in the meat, and poultry, seafood, produce, medical and pharmaceutical industries.
