Freestyle Skateboard Skidplates

Freestyle skateboards typically have skidplates (a.k.a. "tail-savers" or "tail-skids") to reduce the frictional wear on the underside of the deck nose and tail. Avoiding wear on the nose and tail is important for freestyle boards as there are many tricks that excert a lot of force on the ends of the board which, if worn down too far, will delaminate and ruin the deck. Freestyle skidplates are typically plastic or wood and are bolted or screwed to the deck. Plastic is preferred as it offers less friction. There are very few commercial outlets for freestyle skidplates, mostly from specialist skate shops in the USA and Germany.
