The  Universal Snow Thrower Poly Slide Skid Shoe Kit is a great alternative to replacing traditional metal skid shoes. Constructed of rust-free, long lasting poly resin, and featuring a reversible wear use design, these skid shoes will get the job done longer and eliminate unsightly rust. Poly resin construction allows skid shoes to glide on surfaces during snow removal, which reduces and/or prevents damage to driveways, sidewalks and other surfaces constructed of asphalt, concrete, wood and stone.
