For most folks, once they're semi-regular runners, cost and turnover of shoes becomes a factor.
Running has an entire spectrum of needs, personally If Nike is shocked $75-$80(mid $50s after discount https://www.nike.com/w/mens-running-shoes-37v7jznik1zy7ok?sort=priceAsc) isn't competitive with pricing for other brands (Asics and New Balance are easily had for mid-$30s on sale) then I have a bridge to sell them. I(with most people) are not training for Boston, and don't want or need whatever bullshit is sold along with 2-20x the price tag for a pair of shoes to sweat in.
Feigning surprise their incredibly expensive pricing which pushed away the top of their marketing funnel impacts the middle and end of their funnel should be shame on their marketing and analytics team. That goes for any sport, their shit is overpriced and I couldn't give a shit about their brand.
I change shoes when there is a problem. I buy ahead when there are sales so I usually have the next pair already when it's time to change but the most common reason I change is because there is a flat spot in the tread. If you get a blister it's time to change shoes, if you're not getting enough traction while running it's time to change shoes, if you're feet hurt more than normal for a few runs it's time to change shoes. Also make sure you're wearing good socks because they will help prevent issues and extend the life of your shoes and a little talc in your shoes will help them dry out faster which will extend the life of your shoes and help with odor.
