I thought these were pricy when I purchased them, but after over a month of use, they are worth every penny. I destroyed the standard tips within a week of getting crutches. I have had these on for over a month now and they dont have a single mark on them. I'm not sure I could break these rubber tips if I tried to. It is also worthwhile to note that these provide a much more stable platform than standard tips even stable on uneven and wet ground.
