Real Athletes, Real Relief
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 “Zero-Bulk” profile cushions impact before it reaches the tender heel bone — slim enough to fit inside cleats, spikes, and high-tops.
Why KidFormance Wins
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.

Backed By Real Sports Science
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.
They Were Skeptical Too
Real reviews from parents who tried everything else first.
“As a parent, you’ve been such a gift to my family. My son went from crying after every football practice to playing with a smile on his face.”
“We tried ice, heel cups, expensive orthotics and nothing worked… Within a week or two he was back to his old self, playing full games without wincing.”
“My 11 year old daughter was ready to quit basketball… They had her back to 90% in just 5 days. I actually cried watching her sprint down the court with a smile instead of a grimace.”
“The doctor said ‘just rest for 6-8 weeks’ — right in the middle of club season! Jake played his first pain-free game in months.”
