These are my Mizuno Enerzy. They are only a few years old, but they survived my 110kg to 75kg, 5km in 50 mins to 10km in 55 mins fitness journey. Its getting a bit embarrasing at the gym when people see the duct tape. Ive already stitched the holes up three times.
How long are running shoes supposed to last you? They are expensive! Are they expected to do this, or should they last much longer?
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.
