4 in 10 Tennis Players Have Had Tennis Elbow. The Odds Get Worse With Age.
Sometimes it’s the league player. Sometimes the doubles regular. Sometimes the guy who has played five days a week for 20 years.
Most of them were just playing tennis.
It never takes much.
A long Saturday of doubles, and that’s enough.
So is a new racket strung too tight.
So is a week of hard serves with the handle clamped in your fist.
One 4.0 player finished 90 minutes of nonstop serves. An hour later, in his words, he “couldn’t handle a glass of water.”
Five months and two physios later, it still hadn’t gone.
That’s how it gets you. It starts as a sore spot on the outside of the elbow.
Then it hurts to lift your coffee.
To shake a hand. To carry the shopping.
And then it isn’t about tennis anymore.
Players Try Everything. It Still Takes Seasons From Them.
You rest it for a week. It fades. You play. It’s back.
So you buy the lighter racket.
You drop the string tension.
You strap it. You book the physio.
One player listed the lot: technique work, PT, acupuncture, time off. “Have had it for a yr & 1/2,” he wrote.
He’s not unusual. Tennis elbow can drag on for 6 months to 2 years.
And in one Mayo Clinic study, about 1 in 10 patients still in pain after 6 months ended up having surgery.
Meanwhile, your Saturday doubles slot goes to someone else.
The bag moves to the garage.
Unfortunately, almost nobody checks the one thing every one of those fixes skips.
The part you’re actually holding.

Introducing the Octopus Undergrip, the Layer That Stands Between Your Elbow and Every Hit
Under your overgrip is a strip of foam. It came with the racket, and it has been packing down ever since.
Play on that foam and two things happen.
The shock goes straight through. Every ball sends a shockwave down the frame, into your hand, and up to your elbow.
And you squeeze. The handle stops feeling secure, so you clamp down. All that tension runs up your forearm to the same spot on your elbow.
So we built the Octopus to do those two jobs, and nothing else.
The silicone bumps take the hit.
Then they push back when you squeeze, so your hand can’t clamp down the way it used to.
And it’s no thicker than the factory grip it replaces.
Same racket. Same strings. Same swing.
No matter your age, your level or your technique.

Every Hit Is a Landing. What Is Your Arm Landing On?
Your arm absorbs hundreds of these in a match. Now picture jumping on each of these, all afternoon.
Why You Can’t Death-Grip an Octopus
Look at your hand at 30-40 in the third set.
Knuckles white. Forearm hard as wood.
That’s the death grip, and it’s one of the reasons this starts at all.
Every time you clamp down, tension runs from your fingers up your forearm and into the tendons on the outside of your elbow. Then the ball hits, and the shock travels through an arm that’s already locked.
Your coach tells you to relax. At 30-40, your hand doesn’t listen.
The Octopus doesn’t ask.
The bumps press back into your fingers. Squeeze harder, they push harder, and your hand backs off by itself.
“…so that you won’t have a death grip on the racquet and develop tennis elbow that way.”Player on r/10s, on what a cushioned base grip does
So Simple You Forget It’s There
Fit it once, where the factory grip was.
Wrap your usual overgrip on top, same as always.
That’s it. There’s nothing to remember mid-serve. No strap to adjust. No new racket to get used to. No new swing to learn.
You change overgrips like you always have. The layer doing the work stays put.
And when you buy your next racket, peel it off and move it across.
You just stop thinking about your arm.
We’d Rather Refund You Than Argue About It
Think of your order as a 60-day trial.
Order today. Press your thumb into the bumps. Fit it, and play with it.
Then take the full 60 days to decide.
If you don’t feel a difference, send it back. Full refund, and the return is free.
You either keep the grip that works, or you get every cent back.

Frequently Asked Questions
Will this fix my tennis elbow?
No grip fixes tennis elbow, and anyone who says so is overselling. The Octopus is designed to absorb vibration at the handle and take away the need to squeeze. Those are two things your arm deals with on every ball. It is not a medical device or a treatment. If the pain is persistent, see a doctor or physiotherapist.
I already changed my racket and strings. Why would this help?
Because neither of those changes what your hand is holding. A new racket usually ships with the same foam base grip. The Octopus changes that one layer and leaves the rest of your setup alone.
Will it make my handle thicker?
No. The Octopus is the same thickness as a standard base grip, or thinner. Your handle stays the size you’re used to.
Is it hard to fit?
Not with the tape-and-spray method. Strip the old grip, tape the handle, spray the handle and the grip, then slide it on. It needs 12–24 hours to dry, so fit it the night before you play. Stuck? Email us. A founder answers within 24 hours.
Is this an overgrip?
No. It’s a base grip. It takes the place of the factory grip on the bare handle, and your usual overgrip goes on top.
Will I lose feel?
Foam is what deadens a handle. The Octopus compresses on impact and springs back, so the racket stays responsive. You’ll know inside one basket of balls.
Which rackets does it fit?
All standard tennis rackets. Octopus versions for padel and pickleball are sold separately.
What if I change my mind?
Feel the difference in 60 days or your money back, and returns are free. Write to support@rocketgrip.eu and we’ll handle it.
How fast will it arrive?
Orders are processed within 1–2 business days, and most arrive within 3–7 business days with tracking.
