Initially, I worried that these pads would be too small, but that's not the case at all. They're adjustable... and fit my daughter two years ago when she was six, and still fit her fine today. In that time they've withstood multiple spills from the skateboard. They're scuffed, but have suffered no cracks, chips, dents or other damage. I'm very pleased that such a minor investment in safety has lasted this long (and should continue to last for several more years).
