Because my job depends on my feet (nurse) I spend $275 - $300 every 4 - 6 months on shoes that never see the outside world.
I will then bring them home for coop shoes or running errands at home that sort of thing.. but If I try and get more time out of my work shoes my back bothers me and my knees , and ankles.
I have really flat feet and I pronate (feet roll inward) I have been told by the podiatrist that i will only last about another 10 yrs as a nurse, i will then have to go to a desk kind of job like in a drs office, or risk severe disabilities in my golden years
The bonus part.. I donate a lot of my shoes that still look brand new to a local womens shelter
