To my knowlegde these are vintage “skips”, “regects”, or “generics” that kids would get when they really could not afford a pair of name brand sneakers. Kids in those day (1970’s- 1980’s) hated to be seen wearing this type of sneaker because it meant they were poor & had no style.
Some of you might even remember a jingle that went like this:
“Regects, they cost $1.99.
Regects, & they fit so fine…”
I don’t remember the rest. If you do please post it!!
