When not to compare directly

Do not compare them directly when evaluating rigid traditional medial posting or aggressive speed-day racing shoes, as both models are specialized daily stability trainers utilizing non-invasive guidance methods (FLUIDSUPPORT™ geometric design vs. holistic GuideRails® bumpers) rather than stiff medial posts or carbon propulsion plates.
