I'll try my best to describe them seeing as how it's been so long.
They were a pair of kids sneakers from around 93-95 probably.
The sides and back had this clear plastic section which was filled with this green, metallicy gel substance. If you kind of pressed down on it with your finger it would swirl around a bit. They might have been velcro straps as well...
I would appreciate any help trying to remember these shoes...I can't think of the brand or style or anything about them other than that. Thanks!
