Haha freeline skates are quite amusing. Never have witnessed them in real life yet though.
Could always start learning them yourself? Then you’d get to see them in action first hand 😉.
It’s quite cheap to buy an off-brand pair on eBay. I got a pair (they’re branded “Drift Skates”) for £12 and have been using them for almost a year now. I also have JMKRIDE skates, but haven’t used them yet. If you do go for off-brand skates, you should probably also get higher-quality bearings and grip tape. The stock bearings didn’t last long for me and I wear down the Jessup Ultragrip I use so quickly that I have to replace it about once every 2 months.
For actually learning to ride, JMKRIDE has a great tutorial playlist for beginners.
