I realize this is an old thread, but this article about running shoes by the NYT appears to be pretty decent (I'll admit that my positive view of the article may be due to confirmation bias because the article seems to be generally consistent with my own views).
Using different shoes on different days (e.g. with different drops) seems to maybe, possibly, make a slight difference for me in terms of avoiding injury.
>>>Stability and motion control shoes, for instance, are popular among runners and are said to prevent injury by correcting for over-pronation — when your ankle collapses too far inward as you walk or run. Some models have rigid posts that reduce side-to-side motion, though many newer releases use subtler systems, such as making the shoe wider on the bottom than the top, Dr. Klein said.

But current evidence doesn’t bear out their
protective benefits. Pronation itself is a
natural part of your running gait. “That’s how your body dissipates force,” Dr. Vincent said. Overcorrecting it may cause knee and hip pain, and prevent you from properly using and strengthening muscles in your foot and leg. . . .
Ultimately, the idea that any running shoe can prevent you from getting hurt doesn’t hold water. Rates of running-related injuries, such as shin splints and stress fractures,
have remained high over the past 40 years — despite evolving shoe technology. And a Cochrane Review published in 2022
assessed 11,240 runners across 12 randomized controlled trials, most of which compared different types of running shoes to each other. The analysis found no evidence that running shoes, or prescribing certain shoes by type, have injury-preventing properties. . . .
There’s also
some evidence that cycling through more than one model — whether it’s in a different category, or a similar style in different brands — reduces injury risk, perhaps because it slightly varies the repetitive stresses on your body. <<<
It’s tempting to believe the right sneakers will help you run faster or avoid injury. Here’s what experts know.
