I bought some used skates once thinking it was a good deal, but after two weeks the bearings started making weird noises and it became impossible to pick up speed - and that's when I realized the internal wear isn't visible at first glance. The thing is, second-hand skates can work fine if you know what you're looking for (wheels spinning freely, no cracks in the boot, a solid fit), but if you don't have the experience to spot those things, the risk is pretty real. The tip is to try the equipment before you buy, or if it's an online purchase, go with a seller who has a solid track record and gives a really detailed description of the condition.
It depends a lot on the condition of the skates and whether you already know how to skate, because worn-out equipment loses performance and can be dangerous. If you're just starting out, it's better to invest in something in good condition or rent, because worn wheels and bad brakes make a big difference in safety.
The biggest risk with used skates is not being able to tell if the bearings are actually good just by looking - you might be buying something that seems fine but is seizing up inside, which kills your speed and control right when you need them. Beyond the obvious wear that other people mentioned, keep an eye on the boots too: if they've lost their lateral support, you'll end up unstable even if everything else is okay, and that's pretty dangerous when you're braking or turning. If you're really set on buying second-hand, try to test them first (or at least ask for a 48-hour return if you're ordering online) - it's not like buying furniture where you discover the problems later; here you're talking about safety.
Did you actually test the skates before buying, or are you just looking at pictures?
Because the real issue isn't just the bearings - it's that you can't know if the frame is bent or if the boot is cracked. You'll feel skates with a warped chassis on your first turn, but some people don't notice until they fall or try to make a sharp curve. And then it's not just about performance, it's a safety thing.
What I'd do before closing any deal is ask to test them in person. You put them on, skate around for a few minutes in a calm space, feel if there's any weird vibration, if the brake responds right, if it's pulling to one side. If the seller won't let you do that, honestly it's a red flag. Used can be a great deal, but it needs a proper check - more than just looking or reading the description.
