I wear mine after a long day on my feet at work. I have slept with them on also. They help and make my arches feel better. I have worn them during the day while I'm out and about and they are good.
I loved these supports. They helped with my foot pain. However. They do run a tad smaller than expected.
I really love this sleeve. It provides pressure for my currently ailing foot in all the right places and still allows me to wear sandals since it is summer.
Work well, support good, wash well.
My planter fasciitis went away quickly with these.
