Injection molded seamless construction provides 100-percent waterproof protection. Composite safety toe meets or exceeds ASTM F2413 M/I/C. Flexible upper material stays supple in cold temperatures to make walking easier. Tough outsole material for good abrasion resistance. Self-cleaning, cleated outsole spits out debris as you walk.
