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?
My Mizunos (Wave Riders) usually last between 900 and 1100 km. The moment I start having niggles in my knees or hips, I know it's time to move them to my yard work rotation. Seriously, it's not worth tisking an overuse injury running in worn-out shoes, especially ones that provide such a good value as Mizunos.
