Narrow - Narrow wheels have the least amount of traction and are intended for advanced, tech riding.
Treaded - Treaded wheels provide improved grip and traction on smooth surfaces.
99a - Best used in pools and parks with a little more grip than harder wheels, and a little more slide than softer wheels. Ideal for moderately skilled riders who also want to skate street when needed. Hard enough that sliding is a breeze while soft enough for a smooth roll and plenty of grip.
Most urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.
