are rubber soles slip resistant
A slip resistant outsole is softer, and made of rubber that is more slip resistant when exposed to water and oil than other outsole compounds. This softer rubber outsole means that a slip resistant shoe can more effectively grip a slick floor. This means even on quarry tile or hardwood or linoleum flooring, a slip resistant shoe will be able to grab hold whereas a shoe with a harder, stiffer outsole would not be able to.
