Ive always bought these for my kids through the years, But I bought a cheap pair of shoes in a pinch on a family vacation. My son complained of painful legs, all they way up to his hips. Concerned, I took him to the dr. He recommended over the counter insoles and if he wasn't better in a week we would need to take him to a specialist for better support. The insoles were terrible, didn't fit in his shoes with his feet and weren't comfortable. I shopped the malls trying to find an athletic shoe with good support with no luck. I bought these with the hope of avoiding the alternative, expensive and time consuming Dr visits. They did the trick! Within a couple of days he was back to normal. Should have stuck with tried, trusted and true to begin with.
