Wide - Wide wheels provide more traction and stability at high speed, so you'll be less likely to slip out of your line.
Smooth - Smooth wheels have less surface friction than treaded wheels and are easier to slide.
83b - Most urethane skate wheel durometers (hardness of a wheel) range from 75a-101a, the higher the number the harder the wheel.
While most industry skate wheels use the standard “a” scale when determining wheel hardness, the “b” scale is 20 points lower than your typical “a” scale, meaning the hardness of an 83b wheel would in turn equal a 103a in hardness which would be beyond the limitations of the “a” scale.
Gumball Core - Powerflex's 55 durometer core not only allows for a great spin, but it also absorbs more shock than what a single pour 83B/101A wheel ever could.
