What type of shoes are best for working in a hospital?

While expensive, I like Birkenstock and Dansko. Both are available with closed-ankle if you facility doesn't allow clogs for those in direct patient care.

The majority of hospital workers I know use Dansko. They tend to offer the most support to the feet. He may also want to consider getting some orthotics made to help as well.

He also needs to remember to change his shoes every 6 months.

What he may want to do is go to a private shoe store that offers high end professional shoes. The people there can work with him to figure out his gait and what kind of specific support he needs. I wouldn't put someone who supponates into a pair of Dansko clogs or Pros just as I wouldn't put someone with wide feet or high arches into Birkenstocks.

But, a good pair of supportive cross trainers, fitted by a professional (not foot locker) who can do a gait analysis, could also work. Especially if he throws in some orthotics. I know at least 2 foot surgeons who wear cross trainers in the OR.

You should look for some good supporting shoes that have good arches, and lots of support near the top of your foot. The athletic type are usually the best i.e. running, etc., as they usually have a lot of support. You should steer clear of the shoes that you can break in half, or twist at the arch, as they have no support.
