Robalon material is salt, age and wear resistant, lasting up to five times longer than painted steel skid shoes and up to four times longer than stainless steel or molded plastic skid shoes. And because they aren't made from steel, rust spots from old skid shoes on garage floors or scrape marks in driveways, sidewalks and patios are now a thing of the past. Unlike many OEM skid shoes, Robalons are reversible which make them more cost effective than a tradition skid shoe. So lose the rust, save some money and help preserve your driveway this winter with a new set of Robalons!
