This is a premium two-piece sole with a chemical-resistant molded-rubber outsole and comfortable cold-blocking EVA-sponge midsole. The midsole on the DS2 uses the same mold as the DS1 outsole unit. The DS2 outsole is designed for use on hard surfaces and features long-wearing outer lugs and highly slip-resistant bi-directional inner lugs in the forefoot and heel areas. The toe and heel bumpers are designed in the same manner as the DS1; maximum toe and heel protection with large kick spur for easy-off convenience. This sole is resistant to all barnyard chemicals including ammonia, natural acids, gasoline, motor oil, diesel fuel, commercial detergents and diluted muriatic acid.
