What do you wear on your feet?

I need shoes that are easy to slip on and off for when we’re transitioning back in from outside. I have been working at my centre for 5 years, and I’ve worn crocs since I started. However, I have slipped on a few occasions when I didn’t realize the floor was wet, and I even broke my toe once because of slipping on wet floor. Crocs just have terrible grip lol so looking for what everyone else uses !
