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.
Smooth - Smooth wheels have a shiny coating on their surface that is commonly referred to as its skin or mold release. Smooth wheels are generally preferred for their grip and traction.
80a - Soft with plenty of grip. You'll be able to smoothly roll over rough surfaces without getting hung-up on cracks or small rocks. These wheels are slightly harder than the standard 78a and are easier to initiate into slides and drifts. They offer great slide control and are more durable, but won't slow you down as quickly as 78a wheels. Ideal for cruising, carving, freeride, and downhill. Also a good filming duro as its a bit faster than some of the softer varieties.
Urethane skate wheels generally range from 75a-101a, the numbers increase with the hardness of the wheel.
