As is the case with any used equipment, there will usually be some kind of wear and tear. When it comes to picking out a pair of used inline skates, though, you’ll want to make sure that a few key parts are in good condition for performance and safety.
Boot
The most important part of any skate is the boot. Scuffs and scratches are fine, but you should pass if the boot is either cracked or significantly softened from extreme usage as this will compromise performance and support.
Liner
The liner of the skate is crucial as well as it impacts your fit and comfort. Liners can become compressed over time with use, making the skate feel less snug on your foot. A less-than-perfect fit can be tolerated when buying used, but any pain or pressure is a problem.
Chassis/Frame
The chassis or frame is what connects the boot to the wheels, making it one of the most important pieces for performance. As with the boot, you’ll want to make sure that the chassis is not cracked or loose. Depending on the skate, a loose chassis may be a quick fix with a screwdriver or Allen key.
Wheels
Well-functioning wheels are obviously important for any inline skate, but the good news is that they can be replaced quite easily (and cheaply) compared to other parts. If the wheels are badly worn or uneven it’s probably time for a change, but don’t let this be a dealbreaker when buying used if the rest of the skate is in good shape.
