USD Billy O'Neill Breakdown: The USD UFS Throne design provides you with a flexible v-cut cuff to give you the flex you need on grinds and the USD 2 piece soul plate system for your ultimate grinding weapon. The Sifika O'Neill pro liner is definitely one of Sifika's best designed liners yet with a neoprene toe for comfort, inner ankle gasket w/ quality velcro for good ankle support and to help keep your foot in place, and a liner lace to properly tighten the liner around your foot for a good fit.

Overall the USD Billy O'Neill is a great boot to start with as it allows you to bolt on any of the aftermarket UFS frames and compatible wheels and bearings you choose.
