Ewwwwww yuck awful
Color: Large - Obsidian Oasis
Gel moisturizer Sounds like a great idea right?? Ewwwwww! It’s so gross! They are hot feeling, sticky, and sooooo slippery. I was hoping to wear them overnight to help my dry cracked feet but you can’t walk in these! Not even to the bathroom. Honestly I wore them once, saw no difference, and threw them in the garbage.
