Make sure you don't have a foot issue. I have high arches and found out I need orthotics due to it. All my weight goes to he front I my foot. Personally all the nursing shoes hurt me I happen to like sneakers. K Swiss are comfy or new balance. Stay away from mesh, they offer no protection against bodily fluids lol
I wore a pair of Reeboks designed for people that work on their feet while I was in school. Now that I'm an RN working 12 hour shifts, I wear my trusty Adidas sneakers that I've had for a few years, but I think I'm going to get a new pair soon. My feet never hurt, but I also worked a job prior to nursing school where I was on my feet 8+ hours a day, so I'm used to being on my feet. Danskos just look uncomfortable to me, and I also have no arch issues, so I stick with sneakers.
I've had spring step, nurse mates, K-Swiss, Skechers, until I have found my TOP nursing shoes...Danskos! Especially the closed heel...less ankle rolling, and I find them very comfortable for long hours, and the usual "spills" of nursing care, if you know what I mean...if I am in a sneaker mood, Nikes, adidas, or Saucony do the trick...though right now I am REALLY partial to my Danskos!
