The important thing I've seen from foot doctors is to rotate through your shoes. Even subtle differences help move contact points around which in turn changes which how the musculature responds. Share the load around.
I wear leather clogs made by Dansko. Great arch support and the thick leather provides good protection for the feet. I have a concrete floor and can stand up all day w/o discomfort. The brand was recommended to me by my physician and my ER nurse (wife).
Made with durable, waterproof leather and featuring a moisture-wicking lining, these steel toe shoes will keep you cool and dry. Reflective safety feature runs from heel to toe for added visibility on the job
Skechers also makes "Work" steel toe shoes that look a lot like those Keens. I got mine at DSW a couple of years ago and they've held up well. They are also significantly less expensive. They are also available on Amazon.
