We have 2 pairs of Heelys, both men's size 9. One is ProPel 2 and the other is VOPEL. We bought them for our boys who outgrew them before barely using them. They are in practically brand new condition, very clean, never have been outdoors. One even still has part of the original store sticker on the sole! We have the user's instructions and kits for replacing the wheel with a flat spacer. They were $110/pair new and would like to ask $75 per pair.
