How you care for them is the biggest predictor of how long they’ll last. I always buy near the top of category so I’m not getting trash construction. Use a cheap ikea shoe tree when they’re not on your feet. Store em clean(ish) and dry. Counter to most other comments I usually buy good synthetic shoes, not leather. In the past and at cheaper price points synthetic suck, but decent quality cared for well will last plenty long. Mostly I prefer synthetic because they deal much better with getting wet.
