I bought these for a job in a bakery where I'm standing for 6-8 hours a day.  I've worn them twice now and my feet don't ache at the end of the day!  Good support for feet but also supports the back, it seems.  I bought them at my normal size, but they were a tad too big.  Wearing thicker socks fixed that.  I also love that these slip on and off and do not require shoe laces.  Definitely recommend!
