See how KidFormance works for Sever's disease and the growth plate
Compress
Graduated compression zones wrap the heel and ankle, supporting circulation and helping calm inflammation around the growth plate.
Stabilize
The cross-strap system acts like an external ligament, deloading the Achilles tendon so it stops tugging on the growth plate with every step.
Absorb Shock
The slim-fit profile cushions impact before it reaches the tender heel bone — slim enough to fit inside cleats, spikes, and high-tops.
Built for growing heels, not generic feet
Targeted Heel Support
Compression is concentrated right where Sever's pain lives — around the growth plate — instead of squeezing the whole foot evenly.
Step-by-Step Cushioning
A shock-dampening layer takes the sting out of every landing, so hard courts and turf don't punish young heels.
Circulation-Boosting Compression
Graduated pressure zones keep blood moving and help calm the inflammation that flares up during activity.
Wear-It-All-Day Feel
Light and breathable enough to stay on from first bell to final whistle — practice, school, and everything between.
How KidFormance compares to gel heel cups and generic compression socks.
No paid doctor, no fake study — just the published research on Sever's disease itself.
A systematic review of treatments for calcaneal apophysitis (Sever's disease) found only a small number of controlled trials existed and called for further research — while noting taping, heel lifts, and orthotics are widely accepted management approaches.
Read the study →A review of 17 peer-reviewed studies found heel lifts provided short-term benefit and physical therapy supported a return to sport within roughly two months.
Read the study →Standard clinical reference guidance recommends evidence-based conservative management — activity modification and proper footwear support — as first-line care for Sever's disease.
Read the reference →A systematic review of 8 randomized controlled trials found insoles, physical therapy, and Kinesio taping each had a positive effect on reducing pain and improving function in children with Sever's disease.
Read the study →These studies examine general conservative approaches to Sever's disease — heel cushioning, taping, orthoses, and activity modification. None of them are clinical trials of the KidFormance sleeve specifically, and no independent study of this product has been published. Always consult a physician for diagnosis and treatment.
Real reviews from parents who tried everything else first.
"I was ready to give up. Three specialists, custom insoles, weeks of rest,nothing kept my daughter on the track team. These were the first thing that actually let her run without wincing. She ran a personal best last weekend. I'm still in shock."
Samirah P. — Football Parent
"We spent a fortune chasing a fix — night splints, gel pads, two rounds of physical therapy. What finally worked was so simple I almost didn't order it. By the second week my son was jumping into full soccer matches again like nothing ever hurt."
Gina A. — Football Mom
"My 10-year-old told me he wanted to stop playing hockey because his heels hurt too much to skate. I figured we'd try one more thing. A week later he was flying around the rink again, laughing the whole time. I got a little emotional watching him, not gonna lie"
Rebecca L. — Basketball Mom
"Our pediatrician basically told us to shut it down for two months — impossible with playoffs coming up. We tried these instead and my son Ethan finished the tournament without sitting out a single quarter. First time in ages he actually looked forward to game day."

No sales pitch. Just straight answers.
If the pain is coming from the growth plate (Sever's disease), that's exactly what KidFormance is built for. It adds targeted compression, heel stability, and shock absorption around the spot that flares up when kids run, cut, and jump — so they can stay active while it settles.
Yes. The low-bulk build is made to slide into cleats, spikes, basketball shoes, and everyday sneakers without feeling thick or crowding the foot.
Follow your doctor's guidance first. KidFormance isn't a replacement for medical care, but plenty of parents use it as supportive gear once their child is cleared to return, or for extra comfort during everyday movement..
Most Amazon sleeves are plain elastic tubes that squeeze the whole foot evenly and slide around once your kid moves. KidFormance concentrates support at the growing heel, holds position with a cross-strap, and stays slim enough for cleats — designed for the actual problem, not just wrapped around it.
We sell direct so we can control quality, help with sizing, offer bundle pricing, and give real customer support — instead of getting lost among generic knockoffs on a marketplace.
Most do — it's lightweight, breathable, and thin enough that they forget it's on during practice, school, or games. No bulky brace feel, so there's a lot less fighting to get them to wear it.
With normal use and proper washing, one sleeve holds up through regular sports and daily wear. Wash cold and skip bleach, ironing, and fabric softeners to keep the compression and fit lasting longer.
