★★★★★ 4.7 · 224 reviews
It doesn’t squeeze the whole knee. It takes the load off the one point under the kneecap and leaves the rest of the joint free to move.
- Silicone lock-point pad. Grips skin, not fabric.
- Stays put. Stairs, garden, all day.
- Breathable for all-day wear.
- One size. Adjustable, no tape measure.
Most people wear one on each knee, which is why the free ones are doubled rather than discounted.

Materials & build
The pad is soft medical-grade silicone that holds on skin. The band is an open weave, so air moves through it, and a stainless steel buckle keeps the tension where you set it. Nothing rigid, nothing that bulks under clothes.

Everything lands on a spot the size of a coin.
Every stride, every stair, every push out of a chair funnels your body weight through one small area below the kneecap — a patch you could cover with a thumb. That is the patch this strap is built around.
A sleeve wraps all of it and squeezes equally — spread the pressure across the whole knee and you concentrate it nowhere. The strap does the opposite: it sits across the tendon, takes the load off that one spot, and leaves the rest free.
- 01The pad sits across the tendon, a thumb’s width below the kneecap.
- 02The band wraps once and pulls that one point in.
- 03The buckle holds the tension. Everything else stays free.

Six ordinary moments.
A patellar strap was built for runners, and runners still wear one. But the tendon does not know where the load came from — and for most people it arrives from a staircase, a flower bed, or a shift that does not let them sit down. Those are the moments this page is about.
- Coming down stairsKnee already bent, full weight on one point
- Kneeling in the gardenDown, up, down again, twenty times an hour
- Standing all day at workHours of small loads that add up by the evening
- Getting out of a low chairThe push-off everyone starts avoiding
- A long walk or a hillFine on the way out, felt on the way back
- Lifting something awkwardShopping, a grandchild, a bag of compost
Stairs are where you notice it.
Coming down is when most people notice it. Each step puts your whole weight through that one point with the knee already bent — which is exactly the moment the strap is doing its job.
Nobody decides to stop going out on their own.
It goes a bit at a time. One staircase you start taking slowly. Then the shop with the car park nearer the door. Then you let somebody else carry it in. Then someone asks whether you should really be going into town by yourself — and you find you don’t argue.
A strap does not fix a knee, and we are not going to tell you it does. What it does is take the load off the one point that makes you think about a step before you take it. For a lot of people that one thing is the difference between planning the day around the knee and simply going.
- Taking the stairs without looking for the handrail first
- Stepping off a kerb without setting yourself up for it
- Going on the walk instead of waiting in the car
- Carrying the shopping in yourself, in one go
Nobody told you anything untrue.
If someone has said it’s wear and tear and to expect it at your age, they were not fobbing you off. Tendons and cartilage really do change over the years, and no strap is going to turn that back.
But that sentence leaves something out. It explains why the tissue is less forgiving than it was. It does not explain why coming down the stairs is worse than going up. Or why the first few steps out of bed are the worst of the day. Or why it bites getting out of the car after a long drive, and then settles once you’re walking.
Those are not age. Those are the moments when the most load goes through the smallest area. And load is the one thing in that list you can actually change this week.
We can’t do anything about the years. We can take the weight off one point.
Most people have a drawer.
A tube bandage from the chemist. A neoprene sleeve somebody recommended. A box of gel patches. Paracetamol for the bad days. None of it was a daft thing to try — each one does something. The trouble is that none of them do this.
- The tube bandageEven pressure around the whole leg. It feels reassuring and it keeps the joint warm — but it presses the sore spot exactly as hard as everywhere else.
- The neoprene sleeveMore compression, same idea. Holds heat within the hour, limits how far the knee bends, and goes back to square one the moment it comes off.
- Gel or heat patchesWork on the surface and wear off. They do nothing about where the load goes while you are on the stairs.
- PainkillersThey change what you feel, not what the knee is doing. Plenty of people end up taking them before a day in the garden rather than after.
- A strap across the tendonDoesn’t wrap, doesn’t squeeze, doesn’t numb. It sits on one spot about two centimetres under the kneecap and takes the load off it, and leaves the rest of the joint free to bend.
If the drawer already has four things in it, the honest question isn’t whether this one is better. It’s whether it works differently. It does — and you have sixty nights to find out whether different is enough.
The scalpel, not the sledgehammer.
A brace treats the whole knee as the problem and smothers all of it — a bit like bandaging an entire arm for one cut finger.
- Compresses the entire joint
- Restricts how far you can bend
- Holds heat against the skin
- Bulky and obvious under clothing
- Loads one point below the kneecap
- Leaves the joint free to move
- Open weave, nothing to trap heat
- Flat profile, invisible under trousers
Nothing else needed to be there.
Grips, not slides
A silicone pad on the inside holds onto skin instead of creeping down the shin.
Stays put while you kneel
Gardening, DIY, getting down to a bottom cupboard — it holds instead of rolling down the shin.
All-day breathable
Open weave and a narrow footprint, so there is almost nothing there to trap heat.
One size, adjustable
No chart, no tape measure. The band adjusts to slim, athletic and larger legs alike.
Three steps, sitting down.
No measuring, no second pair of hands. If you can fasten a watch strap you can fasten this.
-
Find the spotSit down and put two fingers flat under your kneecap. The soft hollow you land on, about two centimetres down, is where the pad goes.
-
Wrap it onceTake the band around the leg and draw it back through the buckle. The pad sits flat on that spot, the wordmark facing out.
-
Firm, not tightPull until it feels snug, then check you can slide one finger underneath. Stand up and take a step — if it shifts, one more notch.
Find the spot
Wrap it once
Firm, not tightWear it for the thing you are about to do. Most people put it on before the stairs, the garden or the shop, and take it off after — though it is breathable enough to leave on through a full working day.
In their words.

“I'd given up on my garden. Kneeling, bending, digging — it all hurt too much. Wore this strap and spent three hours out there the day it arrived. My daughter couldn't believe I was back at it.”
“Physio told me to try a patellar strap. Sceptical at first but after a week at the gym I'm a total convert. Leg press, squats, lunges, the lot. No aching afterwards. Wish I'd found it years ago.”
“Did a 9-mile coastal walk last weekend with one on each knee. Felt absolutely nothing. I used to have to turn back at mile three. Now I just keep going. My walking group have all ordered a pair.”
“45 minutes on the elliptical every morning and my knee never used to make it past 20. With this strap I'm finishing the full session every single time. Comfortable, breathable, doesn't budge.”
“Played two full sets of tennis without it slipping once. Six months ago I couldn't finish a match. Now I'm back on court three times a week and my knee doesn't even cross my mind.”
“Thought it would look ridiculous under gym leggings. Can't even see it. More importantly, I'm back to leg press and lunges without that sharp sting on the way down. Absolute bargain for what it does.”
Before you buy.
Why not just wear a knee brace?
A brace wraps the whole joint and squeezes everything at once — it limits the bend, holds heat, and does nothing in particular about the spot that hurts. This sits across the tendon below the kneecap and changes where the load goes.
I’ve tried sleeves before. Why would this be different?
Because they were aimed at the whole knee. A sleeve compresses everything evenly and a brace locks the joint, but neither one puts pressure on the tendon below the kneecap, which is where the load gathers. That is a difference in approach, not a promise it will work for everyone — which is what the sixty nights are for.
It looks tiny. Does it really do anything?
Its size is the point. It only has one job — one spot under the kneecap — and anything bigger would press on parts of the leg that do not need it.
Will it fit my leg?
Yes. One size with an adjustable fastening that suits slim, athletic and larger legs alike — no sizing chart, no tape measure. Customers from a dress size 6 up to a 22 wear the same strap.
Which knee, and can I wear two?
Either — it is symmetrical. Plenty of people wear one on each, which is why the second comes free.
I still walk a lot, or run. Is it for me too?
Yes — that is where this kind of strap started. It is the same load on the same tendon whether it comes from a 10k, a hill walk or twenty trips up and down the stairs. We lead with the everyday because that is who most of our customers are, not because it stops working when you pick up the pace.
Will anyone be able to see it?
Under trousers, jeans or leggings, no — it is a flat band with nothing rigid in it, and it does not bulk out the leg the way a sleeve or a brace does. In shorts or a skirt it is visible, and it looks like a plain black band rather than anything medical.
And if it turns out not to be for me?
Email us within sixty nights of delivery and we send a prepaid return label, then refund you in full to your original payment method.
Is this a medical device?
No. It is a support strap, not a treatment, and it diagnoses and cures nothing. If your knee pain is new, severe or came from an injury, see a GP or physiotherapist first.
One point. Not the whole knee.
