Are you wearing sneakers in the snow or winter boots?
If your car has all-season tires it could be like wearing sneakers. It is possible to walk down a snowy, icy sidewalk wearing sneakers--but it's a lot easier and safer to do it in proper boots.All-season tires are designed to cope with all sorts of conditions, including dry roads and rain, but are not optimized for any one condition. They are generally made from harder materials that don't conform to the road surface as well in low temperatures. Snow tires have tread patterns specifically designed to dig down and bite into snow and ice, plus they are made from softer rubber compounds that retain their flexibility in cold weather, allowing the tire to better conform to the surface of the road.
