The shift towards a more comfort-centric design in the Brooks Glycerin 18 raises some serious concerns. If Brooks is indeed targeting a casual market, what does this mean for the hardcore runners who rely on precision and performance? Is it possible that they could inadvertently alienate a significant portion of their user base? Furthermore, if performance-enhancing technologies exist elsewhere, why can't Brooks adopt similar strategies to maintain responsiveness while offering comfort? Are we witnessing a trend where companies sacrifice performance for market expansion? What innovations could potentially bridge this gap without compromising the needs of serious athletes?
