Which walker should not have rubber tipped legs?

Walker types that typically should not have rubber-tipped legs include those designed for outdoor use, such as all-terrain or heavy-duty walkers. These walkers often utilize wheels to provide better maneuverability on uneven surfaces and may require a more stable base without rubber tips to prevent slipping. Additionally, certain types of medical walkers, like those used for rehabilitation, may also be designed without rubber tips to facilitate specific movements or exercises.
