On the run

Beast / Ariel GTS 26: Maximum support for walking and easy miles. Very supportive, with front-to-back GuideRails that are prominent but well integrated. Best for walking and heavy heel strikers; the midsole feels limited for running.

Beast / Ariel GTS 24: The max-support workhorse. Unmatched stability with a firm, substantial midsole. Exceptional for heel strikers and walking, but heavy and not for forefoot strikers.

The Beast / Ariel GTS 26 hasn’t been lab tested by RunRepeat yet, so its feel ratings are estimated from the Beast GTS 24 lab test (RunRepeat) and Doctors of Running’s review of the 26.
