Took a few tries to get them underneath the skates but once we figured that out they work great. All of my grandsons (5-10) use them and like them better than another brand we tried because they’re heavier.

The velcro could be a little longer to get to strap better. My son loves them, seems to be doing the trick.

I thought the quality was good but I’m going to need to adapt the straps to fit my sons skates. If the Velcro went further down the strap they would have fit.

My 14year old boy requested those weight to improve. He even put them on in power skating exercise. He really liked it. Feeling his legs working even more. Great quality easy to put on and off.
