My son just turned 5. I was impressed how well these fit him. Just make sure you buy some long soxs that go above the knee because the top straps rub the back of there legs
They were long for my grandson he's on the short side
My son is 4 Years old and weighs about 39 lbs I was afraid these would not work ,but they fit perfect he has wore them many times and there has been no issue's at all fit like a glove if your child is between 4-5 these will work perfect.
