I am lucky I have a wide range that I find comfortable, because the $30 Costco shoes and the $180 On Clouds are all the same to me. I also don't buy them every 3 months, maybe 6 months at most frequent. Last time was probably almost a year ago, and I got 2 pairs, one to keep nice so they're presentable, and the other for literally anything else, and they look terrible, but still aren't coming apart.
