The OP does bring up a good point, albeit in a very trollish way. Some runners have become like a good portion of the cycling and triathlon community: mediocre athletes with money and a gear obsession. The avalanche of online shoe reviews has just accelerated the trend and some otherwise smart people are just suckers for slick marketing.
This goes beyond a few rotating pairs of shoes and appropriate clothes for weather conditions. It is buying every piece of available wearable tech, getting every book about training and trying to put together a plan based on their latest read (their fifth new training philosophy this year), boasting that they just bought the latest and greatest new carbon thing, and trying very hard to look "pro" while not being anywhere close to pro fitness. You know these dudes at your local club and races - AlphaFlys, Coros watch and Stryd pod, Maurten drink bottle, looking very serious about everything during warmup, blasting out a disappointing also ran 5K time and then quick with the excuses afterwards (too hot/cold, too many turns, dumb course with a moderate hill in the final mile, just training through this one, ran 20 miles the day before, walkers in tutus lined up in the "elite" corral, confusing check in process, etc.)
Get back to basics! Commitment to a solid training plan, a simple GPS watch, two pairs of trainers, and a set of flats are all you need.
