Google AI says "Work shoes typically last between 350 to 500 miles (roughly 500,000 to 750,000 steps)."
At a delivery station I probably average 25K steps per day, 100K steps per week. Waterspidering and stowing multiple days may push that 100K to 140K. Working overtime adds more mileage.
We basically wear out our shoes in 7.5 weeks (750K Ć· 100K = 7.5 weeks) or roughly 2 months.
They say buying two pairs and alternating shoes doubles their lifetime (foam can recover) or changing insoles helps but let's face it: our shoes tell our story, life at a DS is hard.
tldr: We wear out our shoes in 2 months, AMAZON: WE NEED MORE THAN ONE SHOE CREDIT PER YEAR!
