Our high-performance ferrules are suitable for most crutches, canes, and walking sticks. The uniquely designed bellows help absorb shock, which in turn can relieve pain and discomfort in the upper body. The flexible bellows help to keep the foot in full contact with the ground significantly improving safety and comfort, even on rough terrain. The spring action also helps to aid walking efficiency reducing user fatigue. Our foot tread provides up to 50 percent more grip than traditional rubber ferrules to help reduce slips, trips and falls. Are you a High Activity user? If you require greater shock absorbency because you are full weight bearing or an active user, all ferrules come with O rings that can easily be fitted to the foot to increase the resistance in the bellows.
