Walkers are noisy. If you’ve ever spent time in a quiet hallway or a tile-floored kitchen with a standard aluminum walker, you know that screeching sound. It’s like a finger on a chalkboard, but worse because it’s constant. That's exactly why people started putting tennis balls on a walker in the first place. It wasn't some corporate design choice. It was a grassroots, DIY solution to a very annoying problem.
You see them everywhere. Hospitals, nursing homes, and your neighbor's driveway. But there is actually a right way and a very wrong way to do it. If you mess it up, you're not just looking at a sloppy DIY project; you're looking at a potential fall hazard.
The Actual Science of Why We Do This
Most standard walkers come with those hard plastic glides or rubber tips on the back legs. On carpet, they snag. On hardwood, they scratch. On tile, they scream. Tennis balls provide a soft, pressurized cushion that mutes the noise and allows the walker to "float" over uneven surfaces like rug transitions or door thresholds.
But it’s not just about the noise. It's about the friction. A standard rubber tip is designed to grip. That’s great for a cane, but for a walker—especially if you're using the kind with wheels on the front—you need the back legs to slide just a little bit. If they grip too hard, the walker stutters. You lurch forward. It's jarring.
What Kind of Balls Should You Actually Use?
Don’t just grab the cheapest ones at the dollar store. Well, you can, but they’ll go bald in a week. If you’re using the walker outside on concrete or asphalt, those tennis balls are going to shred.
Think about the texture. You want something with a thick felt. Some companies actually sell "pre-cut" walker balls that are neon colors or even patterned. They're usually just standard tennis balls with a factory-made slit. Honestly? You can save five bucks and just buy a pack of Penn or Wilson balls and do it yourself. Just avoid the "low compression" balls used for kids' tennis; they're too squishy and won't hold the weight of the walker properly.

How to Put Tennis Balls on a Walker Without Cutting Your Finger Off
This is the part where most people get hurt. Not from the walker, but from the knife. Trying to slice a round, fuzzy, rolling object with a kitchen knife is a recipe for a trip to the ER.
Step one: Stabilization. Do not hold the ball in your hand while you cut it. I can't stress this enough. Use a vice if you have a workshop. If you don't, find a way to wedge the ball so it doesn't move. Some people use a muffin tin to hold the ball steady.
Step two: The Cut.
You don't need a massive gaping hole. You need an "X." Take a sharp utility knife—a box cutter is best because you can control the depth of the blade—and make a small, one-inch slit. Then, rotate the ball 90 degrees and make another one-inch slit crossing the first.
Step three: The Installation.
Remove the existing rubber tips from the back legs of the walker. If they’re stuck, a little bit of wiggle or a squirt of soapy water helps. Slide the tennis ball over the metal tubing. The "X" cut will grip the tube. It should be snug. If it's wobbling, your cut was too big.
The Maintenance Factor Nobody Mentions
Tennis balls are basically magnets for dirt. If you’re walking outside, those fuzzy yellow covers are going to pick up pebbles, sand, and grime. Then, when you come inside, that trapped grit acts like sandpaper on your hardwood floors.
Check the bottoms of the balls every few days. If they look like they’ve been rolling in a gravel pit, it’s time to swap them out. Also, keep an eye on the "baldness." Once the felt wears down to the black rubber underneath, they lose their sliding ability and start to mark up the floor.
Why Some Physical Therapists Actually Hate This
If you talk to a professional at a place like the Mayo Clinic or a specialized geriatric rehab center, they might give you the side-eye for using tennis balls. There are legitimate concerns.
First, there’s the hygiene issue. In a hospital setting, tennis balls are porous. They trap bacteria. You can't really "disinfect" a tennis ball. This is why many modern facilities require "walker skis" or plastic glides instead.
Second, there’s the "tracking" issue. If the ball isn't cut perfectly, it can cause the walker to sit at a slight tilt. For someone with severe balance issues, even a quarter-inch difference in height can feel like a mountain.
Better Alternatives for the Tech-Savvy
If you hate the look of tennis balls or you're worried about the floor-scratching grit, look into Walker Skis. These are small, sled-like plastic attachments that clip onto the back legs.
- Pros: They last longer than balls, they’re easier to clean, and they look "cleaner."
- Cons: They are significantly louder on tile and can be more expensive to replace.
Another option is the heavy-duty glide cap. These look like the standard rubber tips but are made of a high-density polyethylene that slides easily. They don't have the "cushion" of a tennis ball, but they also don't look like you’ve been raiding the local country club's trash bin.
The Safety Checkpoint
Before you commit to the tennis ball life, do a quick safety check.
- Is the walker level? Put it on a flat surface. Does it rock? If it does, one ball might be pushed further up the leg than the other.
- Is there a trip hazard? Sometimes the balls make the footprint of the walker slightly wider. If you're navigating tight spaces, make sure you aren't catching the balls on chair legs or door frames.
- Are the front wheels spinning? Tennis balls only go on the back legs. Never, ever put them on the front if you have wheels. You'll lose all steering capability.
Making the DIY Version Look Less... DIY
If you're worried about the aesthetic, you can actually buy "walker socks." These are little fabric covers that go over the tennis balls. They come in patterns like plaid or solid black. It hides the neon yellow and adds another layer of floor protection.
Honestly, though? Most people just embrace the yellow. It’s a badge of utility.

Actionable Next Steps for Mobility Success
If you're ready to quiet down your walker and make it glide smoother, follow these specific steps:
- Buy a 3-pack of pressurized tennis balls. Brand name doesn't matter much for indoors, but "Extra Duty" felt is better for outdoor use.
- Use a vice or a sturdy clamp to hold the ball. Safety first—keep your fingers away from the blade.
- Cut a small "X" rather than a single line. An "X" provides a much tighter grip on the walker leg and prevents the ball from falling off when you lift the walker over a curb.
- Remove the old rubber feet. Do not try to put the tennis ball over the rubber foot. It won't fit, and it will be unstable. Save those rubber feet in a drawer in case you ever need to use the walker on a very slippery surface where you need more grip.
- Replace the balls every 2-3 months. If you see the black rubber through the felt, or if the ball feels "squishy" and lost its internal air pressure, it's done.
- Check for trapped debris daily. A quick wipe with your hand can save your hardwood floors from permanent scratches caused by trapped sand in the felt.
