Actually, better than I expected!
Size: Medium, Unit Count: 4
These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.

So so...
Size: Medium, Unit Count: 2
They do what they advertised.
You can NOT walk in them you will stretch them and pop a hole in them.
You cannot sleep in them unless your going to wear larger cotton socks with them to keep them in place. They are easy to wash and dry which is nice. I will need to buy another pair. Great if your gonna watch a movie or binge TV in.

Great for dry feet or to help lock in moisturizer or medication
Size: Medium, Unit Count: 2, Size: Medium, Unit Count: 2
They’re stretchy and don’t feel goopy, I use them daily and they’re working great they keep my feet nice and hydrated and soft. I’ve been using them along with lotion to help hydrate my skin so they aren’t rough during the winter. They are comfy and if you must get up they’re grippy and don’t slip or slide they stay put. They’re super easy to put on and take off.
