My feet can get pretty dry in the winter, so I decided to try this out after receiving it from either Ulta as my free birthday gift. I 1000% would give this 0 stars if I could. It says it is a warming foot mask, but says that it is a slight heat and that you are supposed to sleep with it on overnight. I put it on my whole foot, too, bottom and between the toes, put my cotton socks on as the directions say and went to bed. It says the warming may take a few minutes, but in less than 5 minutes, my feet felt like they were on fire! I waited another 10 minutes thinking it would calm down, but it didn’t! It only got worse! Even after washing it off, my feet still felt like they were on fire for a couple hours!
