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 run 500-700km in my shoes before they become my walking shoes. The shoes just can't take it much more and I start to lose traction or feel some discomfort in the feet.
Running shoes are definitely expensive, but if you're running a lot then the possibility of injury exists so I like to be on the safe wide with my "equipment" which is mostly the shoes.
