Neutral and stability comparisons should stay separate
For Brooks and ASICS, first decide which models actually belong together. Ghost 18 and GEL-CUMULUS 27 are neutral daily-training candidates. Adrenaline GTS 25 and GEL-KAYANO 32 are support-model candidates. Comparing Ghost with Kayano without acknowledging that difference risks crediting the brand for a feature specific to one category.
This is a shopping distinction, not a diagnosis based on your arch height. Plantar fasciitis does not automatically assign you to a stability shoe. If a professional has already advised you about support or an orthotic, use that information to choose a more relevant pair to try.
Different support systems need a personal fitting
Brooks uses GuideRails in Adrenaline GTS 25. ASICS uses 4D GUIDANCE SYSTEM technology in Kayano 32. Neither name establishes that the shoe will apply the right amount of guidance for a particular wearer, and stronger-sounding marketing is not a reason to accept uncomfortable arch pressure.
For neutral models, compare how cushioning and upper fit work together rather than focusing on the presence of GEL or a particular foam acronym. Walk with your ordinary stride and note where the shoe contacts your foot. A technology can be present without being the reason a particular pair feels comfortable.
Keep the fitting conditions consistent
Use the same socks and intended insert, and try each pair on both feet. Allow separate lace adjustments: two uppers rarely need identical tension. Check heel retention when changing direction and enough forefoot room during the step, rather than choosing from a seated fitting alone.
If one brand has worked before, identify the model and generation instead of carrying that experience across its entire range. Your next purchase should solve a specific need, such as replacing a worn daily trainer or finding a better-fitting support shoe. Neither manufacturer’s reputation can substitute for that model-level decision.
