These are a pair of JumpUSA Jump Soles, which you can use to increase your vertical leap and speed by building important fast-twitch muscle fibers in your lower leg. They strap onto any normal basketball shoe, and are being offered here in size large (Men's, 11-14). They come with a demonstration DVD that shows the workout program and the correct form to use. I used these when I was younger and still playing basketball actively, and they worked great. I improved my vertical by 6 inches in a relatively short period of time.
Now that I don't play any more, they are just taking up space in a bin. They are in great shape, because I only ever used them indoors, and I steam-cleaned them before I put them away. I can't actually list them as "like-new", because I used them, but you will be getting a product that is basically in that condition.Hopefully these help you get above the rim as well!
