Powell Peralta's new Soft Slide Formula (SSF) will be formulated in multiple hardnesses, is faster rolling, and will outlast anything currently on the market by many times. Super fast, incredibly durable, and they slide. SSF is a new paradigm, opening up even more of our concrete and asphalt cityscapes, roads, and hills to skating. The new G-Slides were built from the ground up to improve roll speed, slide-ability and durability. They have a low profile and feel at home on any type of deck set-up. Push, slap, grind, bomb and slide the hell out of them. Yes, they slide.
