“I bought these because the $5 price bumped my total up enough to qualify for free shipping. However, because they hugged my high arches and greatly aided in my recovery from plantar fasciitis, these copper sleeves are worth their weight in gold! I have a wide foot but high arches and the small worked well for me. I wore them with and without socks, in sandals and tennis shoes, waking and sleeping; they never let me down. Toss into the washing machine occasionally, and you're good to go. I didn't put mine in the dryer because I don't like how heat can degrade elastic and I want these to last as long as possible. They have held up well and I'm so glad I bought them!”
“Feels good when lounging around.I tried to wear them a few times in my shoes and they still felt pretty good during and after. I was working on a project and I wore these for about 3 days standing, walking, running, for about 12-14 hours a day. They did feel better when using them after a long day instead of wearing themDuring the day. I feel like good arch supports we're better in my shoes.Update -I also use these for hot yoga. Barefoot exercises sometimes makes my arches fatigue or slightly ache. My arches used to be stronger back during extreme sports and hours of dance classes and rehearsals. Wearing these makes me conscious of foot placement and alignment so my arches are getting stronger and I my arches don't bother me nearly as much as they used to during classes.”
