I bought a outdoor runner at Lowe's and made my own using grommets I bought at Walmart. Using scissors or utility knife you can cut to length.
The springs on the bottom to secure the covers are from the previous covers.
But they should be available at Lowe's or Home Depot. I didn't want the covers the entire length of the step in case it would interfere with the step operation.
Hope this helps.
