Footwear apparatus for sliding along a rail comprising:
- a shoe including an upper mounted on a sole formed with a downwardly opening cavity;
- an elongated anchor plate disposed over said cavity to engage said sole;
- a slide plate received in said cavity and formed on its bottom side with a downwardly opening trough having a downwardly facing slide surface with a predetermined coefficient of friction for slidingly engaging said rail;
- a fastener device for fastening said slide plate to said anchor plate within said cavity whereby a wearer can run with said footwear apparatus having said slide plate in said cavity and can jump up to mount said rail and slidingly engage said slide surface of said trough with said rail to slide therealong.
