I simply don’t believe this one?
I think we used to call these things “Segs” or “Blakey’s” over here in the UK. I remember the kids at school used to get a card of these shoe protectors, stamp them into the soles of their shoes and then charge about the playground skidding up and down with shards of sparks emanating from the heels. Those were the days!
