I am a teacher on my feet all day and would have a lot of foot fatigue and some swelling by days end. My nurse daughter suggested (actually pretty much forced me) to get these. I was shocked at how much they helped. First time I tried them was at night after getting home to pacify my daughter, and was shocked at the difference just 15 minutes made. I have now purchased a variety of prints and regularly wear them for work. Daughter suggested that I don't dry them, so I don't. Not sure if that is really needed, but not an issue to be cautious.
