Please help identify and by two of these. I know they are 1/2 inch wide and 28 inches long. But the ends did not match any on your web site.

Depending on the size of the bottom piece or the shoe, this could be either the Series 390 or Series 351 depending on the size of the shoe. Please compare your measurements to ours and see what will work for you.
