In the mid 60’s I had an “advanced” board with hard-rubber roller skate wheels on it. They were much smoother than the steel wheels. The only drawback was that if skating on blacktop a small pointed piece of gravel could stick in the pavement and the wheel at the same time. It would make a board go from 20 mph to 0 mph in an inch! You would always need to be prepared to start running at full speed at any time.
Yeah, I had a skinny skateboard in the late ‘70s. That thing was deadly. Between it and lawn darts I don’t know how we survived.
