Although the material that contacts the floor is soft plastic and not some grippy rubber, they still have enough grip with my carpet such that I can feel resistance if the wheels are pointed left/right and I try to move the chair forward. Also, because of the material, the wheels track a surprising amount of dust. Other than that, I think they're great. They are certainly much better than the small casters typically found on cheap office chairs.
