Jelly Sandals My vivid memories of jelly sandals fell into two camps: the smell of the plastic and the blisters they would leave on my feet from rubbing against my skin. You’d think that would’ve deterred me from wearing them, but clearly not! The jelly sandals that are trend these days have improved in comfort, but still have the youthful look from my childhood. And if sandals aren’t your thing, there are flats and slip-on options, too.
