Back in the day when there was only the 1974 and 1986 leg style, Playmobil invented a leg cuff, much like the wrist cuffs that are so common, to indicate that a figure was wearing boots. I've seen them in black, red, and yellow, and they may have come in other colours. They have fallen out of favour now that there are so many leg mouldings to indicate different footwear.
I would call these boot tops, but I can't find anything under that name on the database. Does anyone know what these are called and what the part numbers are?
