I've tried wearing different brands and styles of shoes in the clinic that will protect my feet and stand up to the demands I place on them. Every single pair have split at the ball of the foot due to those demands.
I hesitate to wear sport-type shoes because I don't think they look professional enough in the clinic. I like the feel of Italian leather against my foot and the comfort it provides but any dress-type of shoe seems to wear out just as quickly as the sport shoes I've worn in the past. I want the shoes I wear to complement the outfits I wear so I look professional to clients, nurses and doctors, yet I want to be comfortable when I'm moving around in the therapy gym. Tennis shoes don't work for me unless I'm mowing the lawn or walking the dog.
I've worn boots, which were comfortable but not practical in the clinic. With my supinated foot and sometimes weird gait pattern, I tend to reshape any footwear I try on almost immediately. Currently I have slip-on shoes, which are easy to get on and provide some comfort to my sensitive gait pattern, but they're almost worn out at the ball of the foot as well. I'm not sure if there's a footwear company that can handle the demands I place on my shoes -- providing me with support, comfort and most of all, a professional appearance.
