01
The load funnels
The tendon below your kneecap is the channel everything passes through. Years of steps, stairs and standing all land in the same narrow place.

How do I know I've got it in the right place?
How do I know I've got it in the right place?
Sit down with your leg straight. Find the bottom edge of your kneecap. Place two fingers below it — that's where the pad goes, on the tendon, not on the bone.
Tighten until it's firm and you can still slide a finger underneath. If your leg feels squeezed, it's too tight. It should feel like the pressure is on one spot, not around the joint.
Stand up and walk a few steps. Most people can feel the difference in where the pressure sits within the first minute.
Will it fit me?
Will it fit me?
One size, fully adjustable. It doesn't wrap the joint, so it isn't sized to your knee circumference the way a sleeve is — it's a band with a wide adjustment range.
If the fit isn't right for you, that's what the 60 days are for.
What's it made of?
What's it made of?
Open-weave breathable body with a moulded silicone contact pad that grips skin directly. Adjustable hook-and-loop closure.
Hand wash cold, air dry. Don't machine dry — heat kills the silicone grip.

THE PART NOBODY EXPLAINED
Your knee isn't the problem.
Where the load lands is.
Every step, every stair, every push up out of a chair drives your bodyweight down through your leg. It doesn't spread out evenly. It funnels into one small area below your kneecap — a patch about the size of a coin.
02
A wrap spreads it
A sleeve or brace covers the whole joint. Spreading pressure across everything means it isn't concentrated anywhere — including the one place it needed to be.
03
A strap shifts it
A narrow band sitting directly on the tendon changes where that load is carried. Same step. Different landing point.
If you've already tried everything
You weren't doing it wrong.You were treating the whole knee.
Four things almost everyone tries first — and the reason each one runs out.
The sleeve
Warm, snug, feels supportive for an hour. It compresses everything equally, which means the one spot carrying the load gets no more help than the rest of your leg. Then your leg overheats and you take it off.
The full brace
Bulky, hot, and heavy enough that it works its way down your leg over the course of a day. Half the people who own one have stopped wearing it. It's sitting in a cupboard.
Painkillers and gels
They change how much you feel. They don't change where the load lands. So the moment they wear off, you're back to planning your day around the stairs.
Rest
Sitting still helps, right up until you stand up. Nobody can rest their way through a grocery run, a garden, a flight of stairs at home, or a dog that needs walking.
You know the list
It's never the knee.
It's the things you stopped doing.
Nobody wakes up and decides to give things up. It happens one small surrender at a time, and you don't notice until the list is long.
- Going down stairs sideways. One step at a time, hand on the rail, leading with the good leg.
- The pause before standing up. That half-second where you brace for it before you push off the chair.
- Kneeling. The garden, the bottom cupboard, a grandchild on the floor. Getting down is bad. Getting back up is worse.
- Standing still. A queue, a kitchen counter, a school pickup. Shifting your weight from side to side and hoping it isn't obvious.
- The long way round. Parking closer. Taking the lift. Choosing the flat route. Telling yourself it's not a big deal.
- The end of the day. Everything catches up at 6pm and you've got nothing left for the evening.
If you recognised more than two of those, you already know what this is about.
The three things people ask
Straight answers.
"It'll slide down."
That's the number one complaint about every knee support ever made — and it's usually right. Fabric on skin migrates. The contact pad here is moulded silicone and grips your skin directly rather than gripping your trouser leg. It stays where you put it.
"My leg will cook."
Neoprene sleeves turn your leg into a sauna in about half an hour, which is why most of them come off by lunchtime. This is an open-weave band, not a wrap. Air gets through it. There's almost nothing covering your skin to trap heat in the first place.
"It looks too small to do anything."
It is small. That's the entire point. A brace is trying to hold a whole joint. This is trying to change one contact point. You don't need much material to move where a load lands — you need it in exactly the right place.
STRAP VS. SLEEVE VS. BRACE
Why this one is different.
One contact point instead of a whole wrapped joint.

Sleeves & braces
Targets one contact point
Sits directly on the tendon below the kneecap where load concentrates.
✓
Compress the entire joint evenly, so nothing is concentrated where it's needed.
Stays in place
Moulded silicone pad grips skin rather than fabric.
✓
Commonly work their way down the leg over a day of wear.
Wearable all day
Open weave, minimal skin coverage, no heat build-up.
✓
Neoprene traps heat and sweat, so most people take them off by midday.
Invisible under clothing
Sits flat under trousers, leggings or football socks.
✓
Bulky enough to be obvious under most clothing.
One size, adjustable
No sizing chart, no measuring, no wrong-size return.
✓
Sized to knee circumference, and easy to get wrong.
Wearing it
Two Fingers Below The Kneecap
Most of the people who say a strap didn't work for them had it in the wrong place. It takes about thirty seconds to get right.
1Find the spot
Two Fingers Down
Sit with your leg straight. Find the bottom edge of your kneecap and measure two fingers below it. That's the tendon. That's where the pad goes — not on the bone.
2Set the tension
Firm, Not Tight
Pull it until it's firm and you can still slide a finger underneath. If your whole leg feels squeezed, back it off. You want pressure on one spot, not around the joint.
3Then just wear it
Leave It On
Put it on in the morning, leave it on through the day. Under your trousers, under leggings, under football socks. No routine to remember, nothing to take between activities.
This is a wearable support, not a medical device or a treatment. If your knee pain is new, severe, or came from an injury, see a doctor first.
What people say
Small Thing.Big Difference.
The kind of review people leave once they've stopped planning their day around a flight of stairs.
★★★★★
Stairs feel normal again
I used to take the stairs one at a time and grab the rail before every step. With the strap sitting just below my kneecap, the pressure feels much easier to manage. I wear it for errands and barely notice it is there.

Didn't move once
Every other strap I tried needed pulling back into place after ten minutes. I wore this through a full gym session—squats, lunges and the treadmill—and never adjusted it once. That alone makes it the one I actually use.

The bulky brace stays in the cupboard
I had already bought a sleeve and a hinged brace, but both were hot and awkward under trousers. This is light, easy to position, and comfortable enough for my daily dog walk. I wish I had tried the smaller option first.

One strap. One spot. Two fingers below the kneecap. Most people need two — one for each knee.

Frequently Asked Questions
How is this different from a knee brace?
How is this different from a knee brace?
A brace wraps the whole joint and compresses everything evenly. This is a narrow band that sits on one point below the kneecap, where load concentrates. Different tool, different job.
I've tried braces and sleeves before and nothing worked. Why would this?
I've tried braces and sleeves before and nothing worked. Why would this?
Because those work on the joint as a whole. If what's bothering you is where the load lands, wrapping the whole knee doesn't change that. It's a different approach, not a better version of the same one.
And if it doesn't work for you either, you have 60 days.
It looks tiny. Does it actually do anything?
It looks tiny. Does it actually do anything?
It is small, deliberately. You don't need a lot of material to change where a load is carried — you need it in exactly the right place. Most of the size on a brace is there to hold the brace on, not to do the work.
Will it slide down during the day?
Will it slide down during the day?
The contact pad is moulded silicone and grips your skin directly, rather than gripping fabric. That's the design difference that keeps it in position.
Will it fit my knee?
Will it fit my knee?
One size with a wide adjustment range. Because it doesn't wrap the joint, it isn't sized to knee circumference the way a sleeve is.
Can I wear it all day?
Can I wear it all day?
Yes. Open-weave material with minimal skin coverage, so it doesn't trap heat the way neoprene does. Take it off overnight.
Do I need one or two?
Do I need one or two?
Most people have one knee that's worse and one that's heading the same way. If both bother you, get two — that's what the bundle is for.
Is this a medical device?
Is this a medical device?
No. It's a wearable support. It isn't intended to diagnose, treat, cure or prevent any condition, and it isn't a substitute for medical advice. If your knee pain is new, severe, or the result of an injury, see a doctor.
