What's new in each

Brooks Adrenaline GTS 25: A touch more cushioning with a lower 10 mm drop (down from 12 mm), a refined mesh upper and a knit collar. GuideRails support is unchanged.

ASICS GT-2000 15: A livelier, softer FF Blast Max formula, about 2 mm more stack, a more pronounced rocker, a new woven upper and a redesigned outsole make it lighter and bouncier than the GT-2000 14.
