I'm a PCA on the floor while I'm in nursing school and I'm curious about replacing my shoes. I've read recommendations that they need to be replaced every 500 miles. Needless to say I work 24-32 hours a week and calculated that I walk approximately 6-10 miles per shift. At this rate I'd need to replace my shoes once a month. I currently wear a pair of super comfy New Balance walking shoes which were around $50. I didn't wanna shell out the $120 for Dansko's but now I'm rethinking it.
Do Dansko's need to be replaced as often? How often do you replace your shoes? Is 500 miles realistic or should I look more into the amount of time I wear them (i.e. months)?
