Kintex Youth Heel Support Sleeve - Compression Relief for Active Kids
My son was about to give up football. Two weeks with Kintex and he scored his first goal in months. I cried watching him sprint again.
Will this help my child with Sever's disease ?
Will this help my child with Sever's disease ?
Yes — unlike generic ankle supports that simply add warmth, Kintex was specifically designed for the kind of heel discomfort active kids experience during growth spurts.
The pain your child feels often comes from the Achilles tendon pulling on the developing heel area. Our Heel‑Lock Compression System™ gently supports the heel to ease pressure, while the figure‑8 elastic straps act like an external ligament helping to absorb impact during running and jumping before it travels up the Achilles.
The result? Less discomfort, more time on the pitch, and a child who can finally play freely again.
Will it fit inside football boots, rugby boots, or trainers?
Will it fit inside football boots, rugby boots, or trainers?
Absolutely — this was the #1 request from the UK parents we've worked with.
We engineered the Kintex sleeve with an ultra‑slim, zero‑bulk profile designed to slide inside the tightest sports footwear — football boots, rugby boots, athletics spikes, basketball high‑tops, school trainers, even ballet shoes.
It offers the stability of a brace with the discreet feel of a sock. Your child won't even notice they're wearing it… until they realise the heel pain is gone.
Why is this better than a £10 sleeve from Amazon?
Why is this better than a £10 sleeve from Amazon?
You get what you pay for. Cheap sleeves are just elastic tubes that squeeze the foot uniformly (often cutting off circulation and slipping mid‑match).
Kintex is purpose‑built for growing young athletes. It uses graduated compression zones mapped to the anatomy of a developing foot, paired with adjustable Heel‑Lock straps that let you fine‑tune the tension for your child's exact needs.
You're not paying for a generic sock — you're investing in the targeted support that helps your child finish their season strong, on the pitch where they belong.

'The best decision we made for our young athlete'
My son is back on the pitch — and smiling again
My boy was in tears every evening because of his Osgood-Schlatter. Two weeks with Kintex and he's finished a full training session pain-free. I cried when he came off the pitch smiling. Truly a lifesaver.
£300 wasted before finding this
We tried gel cups, new boots, physio — nothing worked for Harry's Sever's disease. After 8 months of relapses, Kintex finally let him train without limping home. I just wish we'd found it sooner.
He talks about football at dinner again
Osgood-Schlatter had taken my son's confidence. He'd stopped mentioning football altogether. Two weeks with Kintex and he's chatting about his next match like before. Worth every penny.
Finally, something that actually fits a child's foot
Every other sleeve I bought was an adult one cut down for kids. Kintex is the first product that actually fits my 11-year-old's foot inside his football boots. His heel pain is gone after 3 weeks.
No more crying after matches
Watching my daughter limp off the pitch every weekend was breaking my heart. The knee sleeve gave her support exactly where Osgood-Schlatter hurts. She finished her tournament last Sunday — first time in months.
The only thing that fits inside football boots
My son refused to wear any of the gel cups because they slid around inside his boot. Kintex stays put, he barely notices it, and his heel pain is finally under control. I genuinely don't know what we'd do without it.
Our physio recommended it — it works
Our physio mentioned Kintex was a good non-invasive option for Osgood-Schlatter. We were sceptical at first but my son hasn't missed a rugby session in 6 weeks. Comfortable enough for school PE too.
From sitting out matches to scoring goals
Sever's disease had Jack asking to skip warm-ups for 4 months. Three weeks into wearing Kintex and he scored his first goal of the season last Saturday. The look on his face — priceless.

No more pain... just play
Heel discomfort from growing pains, over‑pronation, or intense training sessions... no active child should have to push through it.
Kintex sleeves are engineered for young athletes and growing children who feel heel discomfort and Achilles tension during sport. With targeted Heel‑Lock compression and gentle support, they ease pressure on the heel area, support natural movement, and help young feet feel comfortable through every match.
No more sitting out — just running, playing, and feeling like themselves again.
Designed around growing feet
Most ankle supports on the market are simply adult products made smaller. Kintex isn't.
Every detail of our sleeve — from the figure‑8 strap placement to the graduated compression zones — was engineered specifically for the anatomy of a developing foot. Soft, breathable, skin‑friendly materials let young feet move, grow, and breathe naturally, while targeted Heel‑Lock support gently stabilises the heel exactly where active children need it most.
Because supporting your child's heel shouldn't mean restricting how their foot is meant to grow.
Trusted by sports recovery specialists
As a sports recovery specialist, I work with young athletes every week who are dealing with heel discomfort from growing pains, intensive training, or overuse. The biggest issue I see? Most parents are still using generic adult-sized ankle supports that simply don't fit a developing foot — and that's where Kintex stands out."
"What I appreciate about the Kintex sleeve is its targeted Heel-Lock design — the figure-8 strap configuration mirrors the heel-lock taping technique we use in clinical settings to support the heel during activity. Combined with its slim profile and breathable construction, it's something I'm comfortable recommending to active families looking for a non-invasive way to support their child during sport."
"I always remind parents that nothing replaces proper rest, stretching, and listening to your child's body. But for the everyday moments — training sessions, school PE, weekend matches — Kintex is a smart, supportive option that fits into a young athlete's routine without getting in the way.

Find Your Child's Perfect Fit in 10 Seconds
Not sure which size to order? You're not alone most parents ask us the same question. We've made it simple.
Just check your child's current UK shoe size in the chart below. If they're between two sizes, we recommend sizing up — the sleeve stretches to fit perfectly and feels more comfortable than one that's too tight.
Every Kintex sleeve is designed in the UK to match the unique shape of young athletes' feet, from age 8 to teens.
Got questions ? We've got answers.
How do I know if Kintex is the right size for my child?
How do I know if Kintex is the right size for my child?
Choosing the right size is simple — just measure your child's foot length from heel to toe (in cm) and match it to our Size Guide (S / M / L / XL). Each size also includes a suggested age range and UK shoe size for quick reference.
Still unsure between two sizes? We recommend going one size up — kids grow fast, and the adjustable Velcro fixation ensures a snug fit even with a slightly larger sleeve.
💡 Not the right size? Free exchange — no hassle.
Can my child wear Kintex inside their football boots or trainers?
Can my child wear Kintex inside their football boots or trainers?
Yes — absolutely. Kintex is designed to fit discreetly inside any sports footwear, including football boots, rugby boots, trainers, tennis shoes, basketball shoes, and even school shoes.
The low-profile compression fabric (only 2mm thick) means your child won't feel any bulk or discomfort, and it stays perfectly in place during sprints, tackles, jumps, and quick direction changes.
At what age can my child start wearing Kintex?
At what age can my child start wearing Kintex?
Kintex is specifically designed for young athletes aged 8 to 13 — the age range when growth-related heel discomfort and Achilles tension are most common during sport.
Our 4 sizes (S, M, L, XL) cover children with foot lengths from approximately 18cm to 25cm. Check our Size Guide for the exact match.
How long should my child wear the sleeve each day?
How long should my child wear the sleeve each day?
We recommend wearing Kintex during sports activities, training sessions, and matches — typically 1 to 4 hours at a time. It can also be worn during the day if your child feels discomfort after intense activity.
It's best to remove the sleeve at night to let the skin breathe. For best results, pair daily use with proper warm-up, stretching, and rest days.
Is the fabric safe for sensitive skin?
Is the fabric safe for sensitive skin?
Yes. Kintex is made from a breathable blend of 85% Nylon and 15% Spandex, designed to be:
✅ Hypoallergenic and latex-free ✅ Moisture-wicking (keeps feet dry during sport) ✅ Odour-resistant ✅ Soft against the skin — no rubbing, no irritation
We recommend washing the sleeve before first use, and after every 2-3 wears.
How do I wash and care for the sleeve?

Caring for your Kintex sleeve is easy:
🧺 Hand wash in cold water with mild soap (recommended) 🚫 Do not machine wash on hot cycles, tumble dry, bleach, or iron 🌬️ Air dry flat, away from direct sunlight or radiators ♻️ With proper care, your sleeve will keep its compression and elasticity for 6-12 months of regular use
