I am 5'9" and weigh 220 lbs. Though I quickly wore out the grooves in these little wheels, I get all the grip and speed I need out of them. I have been meaning to replace them since I wore the grooves flat but I continue to use them because they work just fine. I'm very surprised. Very lightweight and dependable for digging in the turns and blazing down the straight way.

I was a little scared when I first put these wheels on my skates because they seemed so narrow, but I've learned now that is one of the advantages of having these wheels. They are lite, and when used with the black pusher wheels, super super grippy. I can cut in and out of the pack without worrying about a big bulkly wheel tripping up other players... I will never buy another pair of wheels....
