I only wore these once. I am aware there is what appears to be a gross stain inside one shoe, but people I'm gonna be honest here...its chocolate. idk how I managed that, but it's freaking chocolate on the inside of the shoe! I am a multi tasker, and I like to eat whilst doing things...like getting dressed and putting my shoes on. there was unnoticed chocolate on my foot, and my foot went in the shoe. 🤷‍♀️
