This base/tip is one of the best devices I’ve ever owned. I have multiple compression fractures in my vertebrae. This tip helps me to distribute my weight at different angles depending upon the distance I have walked and the remaining distance I must walk. I am able to change the angle of the cane relative to my stances which helps me to adjust my gait and move the weight of my body to alternate the pressure of standing and walking among the five badly damaged vertebrae. This is the only tip that allows me to make these adjustments. The tips with four contacts are not as versatile and they exacerbate the pain significantly!
