Like the tires on your car, insoles are the first point of contact between your body and the road. Goodyear brand insoles use high quality materials designed to give you the ride you’ve been missing in your shoes! The ComfortRide 320 insole is a trim-to-fit insole constructed of a high density base layer designed to reduce shock and fatigue from impact energy. A softer memory foam layer conforms to your unique foot shape for maximum comfort. Unique tire tread design helps keep the insole from slipping within your shoe. Anti-Bacterial sock liner helps control odor.
