I’m a bigger guy (over 200 pounds) who runs marathons so my concern is the cushioning and the impact on my feet. I put a 500 km limit on my running shoes, after that they graduate to walking shoes or general gym shoes. My go-to are Asics, and I wait until a new model comes out and then buy last season’s shoes at a discount, anywhere from $60-$110 for a pair depending on what color I want.
Have you tried a physical outlet for these emotions? Hit the gym, or put on some headphones and go for a long run. Running can be very meditative and you can do it pretty much anywhere.
