Searching revisited

Is this a slipper which I see before me? As Macbeth might have asked. I think it might just be, or maybe it's more accurate to call it a sandal. 
Whatever it is, it looks a lot like what I'm looking for. I saw this pic just now at the excellent All Things Spanking and now I want my bot to be next in line to get spanked with that slipper/sandal thingy.
PS Do you ever get those days when you should be working and you try to work, but some part of your brain just can't stop thinking about spanking? I don't know why, but I feel like my SQ is off the scale.
