Narrow - Narrow wheels have the least amount of traction and are intended for advanced, tech riding.
Smooth - Smooth wheels have less surface friction than treaded wheels and are easier to slide.
101a - Essentially some of the hardest wheels in the game. Designed for advanced skating and made to withstand flat-spotting, which can result from excessive sliding with softer durometer wheels. Designed for hard-charging, fast skating in mind.
Standard durometer scale of measurement. Most urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.
