If you mean the little yellow "vibration" balls on the sole. They close like ski boots? I have a pair that I wore 3-4 times. They are very comfy. I have had them for a few years, and didn't wear them, because I forgot I even HAD them. I am a M/C clothing *****.........You looking for some? These are a size 12, but fit like a 11 or 11.5..........LMK.
