“I've been recommending the MASS4D® paediatric insole to my patients for three months now. This product is well-made, and provides a reliable and cost-effective solution to the majority of children with flat feet. The two biggest reasons why I prefer this prefab device over others are – it represents more of a functional heel cup, and it does not interfere with the normal arch development of the child.”

“Love these and they’re such good quality that I ordered 2 more pairs. My twins use them for all their activities also in their rollerblades. They even made some uncomfortable shoes comfortable enough to wear again.”
— Gustav, Parent
"My 8 year old son had heel issues. Immediately he had noticeable relief and definitely didn't complain of pain as much as he had before wearing these. Within 6-8 weeks he had no symptoms at all. He does track 3 days a week so he wears them for that as well. It's definitely worth a try! I will continue to buy them even though they are a bit expensive."
