Standard - Your classic wheel shape, it's not built to excel in specific scenarios like a narrow or wide wheel, but it's appropriate for most situations. If you're new to skating this is where you want to start.
Treaded - Treaded wheels provide improved grip and traction on smooth surfaces.
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.
