The Nike React Infinity Run Flyknit - is it truly a game-changer or just another overhyped shoe? Ive seen some rave reviews, but also some pretty scathing critiques. So, Im curious - for those whove actually put in some serious miles in these shoes, how do they compare to other max cushioning shoes on the market, like the Brooks Ghost or the Hoka Bondi? Are they worth the hefty price tag, or are they just a fancy pair of shoes with a lot of marketing hype behind them? And lets get real - are they really suitable for heavier runners, or are they just a lightweights best friend? Ive seen some concerns about durability, too - have any of you experienced any issues with the sole or upper after a few hundred miles? And finally, how do they stack up against some of the newer, more innovative shoes on the market, like the Alphafly or the Vaporfly? Are they a solid choice for a marathon or ultra, or are they better suited for shorter, more casual runs?
