The Slater Designs 5 Piece Action Pad is Kelly’s favorite arch, with functional design from Kelly directly. He chopped a ‘ V ‘ into the tail kick to prevent your leash from catching and slit the arch. The arch support is just as wide as on our 3 and 5 piece Slater Designs pads but lower on this one. The square grooved edges on either side of the parallel slits give you a ‘hooked in’ feeling that other arch supports won’t, and the Action Pad also gives you options: a longer pad or a shorter pad, depending on how you chose to space the the side pieces from each other.
