These are official PR-7090 Poweriser jumping stilts. They are in good condition with little wear and tear. This specific model is intended for someone between 115-200 pounds. It takes a little while to get used to standing on them but you will soon be able to run and jump around without assistance. These things make dunking easy but walking through doors difficult! They are a lot of fun and also a great workout! Also come with official Poweriser knee guards, wrist guards, and elbow pads. The right person could have a ton of fun with these and show off for their friends with a little practice!
Here is the video that made me buy them in the first place.
