PLASTIC???!!!! noooooo ..... [just being silly here, don't get upset]
Oh Blondie9999 ... type of rubber or something, the originals were of an organic material [made in Canada]. And as the promos went, if one were like, lost in the wilderness and really starving to death, you could boil them and EAT them. [thankfully I haven't encountered anybody that actually did that, but one could --- we cannot eat plastic, those are 'knock-offs' originally made elsewhere and eventually took over the world because the originals were rather expensive, but then you could eat them.] [imagine the story lines for this!]
Aside from the note about plastic, promo looks lovely :-)
Also opens the door for more 'expressions' required for Genesis ... an amazing number of people will produce an amazing number of different expressions when/as they realize the footwear one has on. From the "oh look, another one just like ...." to a hidden smirk of laughter as they try their best not to because in their ignorance they think you came outside in your slippers.
The originals were even permitted in hospitals [for nurses] as they provided traction even on wet floors and were very comfortable. However, as knockoffs became more common and too many people were wounded through the holes up top, they were later banned from hospitals. The originals also had way better foot support and oh I do I miss them. Can't wear the plastic ones.
