How to Replace Crutch Tips (Step by Step)
To replace a crutch tip: confirm the size (7/8 inch is standard), pull the worn tip straight off the shaft, and push the new one on firmly until it seats fully. The whole job takes a couple of minutes and no tools.
Why worn tips matter
The rubber tip is the only thing between the crutch and the floor. As it wears, the tread smooths out, the rubber hardens, and grip drops fast. A worn tip can slide on tile, wet floors, or smooth concrete, which is a real slip hazard. Inspect your tips often and replace them at the first sign of wear, before they fail. This is general guidance, not medical advice.
Signs it is time to replace:
- Tread worn smooth or unevenly
- Cracks or splits in the rubber
- The rubber feels hard rather than slightly grippy
- Any slipping on dry, flat floors
Confirm the tip size first
Most underarm crutches use 7/8 inch tips, and that is the size to start with. But not every crutch matches, so measure before you buy. Check the outside diameter of the shaft where the tip slides on, or read the size printed on your existing tip. Buying the wrong size means a loose tip (dangerous) or one that will not fit at all.
Step by step
- Check the size. Measure the shaft diameter or read the old tip. Confirm 7/8 inch or whatever your crutch uses.
- Buy a matching pair. Replace both crutches at once so wear and height stay even.
- Pull off the old tip. Grip it and pull straight down. Twist while pulling if it is stuck; a little dish soap on the shaft helps with a tight one.
- Push on the new tip. Line it up and push firmly and straight until the shaft seats fully inside the tip. Pressing it against a hard floor helps drive it on.
- Test before walking. Make sure it does not wobble or twist off, then apply weight gently before you rely on it.
When to replace tips
There is no fixed schedule. Heavy daily users wear tips faster than someone recovering for a few weeks. Inspect them regularly and replace at the first sign of the wear listed above. Keeping a spare pair on hand means you are never stuck with a worn tip.
Need new crutches too?
If your tips are worn because your crutches are aging out, it may be time for a fresh pair. See our best underarm crutches roundup for current top picks across budgets and weight capacities.
Frequently asked questions
What size are crutch tips?
7/8 inch is the standard tip size for most underarm crutches. Some crutches use a different size, so measure the shaft diameter or check your old tip before buying replacements.
How often should you replace crutch tips?
Replace them whenever the tread is worn smooth, the rubber is cracked or hardened, or the tip slips on dry floors. There is no fixed schedule; inspect them regularly and replace at the first sign of wear.
How do I get a stuck crutch tip off?
Twist the tip back and forth while pulling it straight down. A small amount of dish soap or warm water on the shaft can loosen a tight grip. Pull, do not pry, to avoid damaging the shaft.
