Never buy shoes again!
There is a reason that we have thick skin on the bottoms of our feet. It is because for hundreds of thousands of years, we walked around with no shoes. Why do we have shoes now? Because everyone is a wuss.
Save money by saving your shoes for when you really need them. Slowly start building up the skin under your feet, and eventually you won’t ever need shoes again. Make sure you gradually make the transition as you don’t want to injure yourself.
I have had the same pair of shoes for over two years now, mainly because I try to keep the wear and tear to a minimum by wearing them as little as possible.
