I love the brand cobbie cuddlers. I have bought them for years for retail jobs, lots of standing, walking runing, etc. They are very nice on the feet, support and cusions where needed.
Mine are butt ugly nurse shoes now, but they were the most comfortable of the stlyes of them I tried on in white, lots of room for the toes on my little weird duck feet. They have lots of styles though for those with non duck feet.
They cost around $25-30. (all styles) within a tight budget that is a good thing, but, one bad point, they don't last really long.
I would say 3 months tops and you have to get a new pair.
