Curious, how do those steer? There's nothing like skateboard trucks or ski & snowboard side cuts or indeed a bike fork to make caster. I had an idea which may be wrong that rollerblades did it with flex in the truck

Edit- clearly wheels want to turn when leaned over, that's obvious. I'm just not seeing how they don't cancel out torque with multiple wheels. They do turn, so this is a conceptual difficulty on my part to work through and not a problem with skates! Different from skateboard / 4 wheel skates because those don't lean the wheels over and must definitely be steered
