Which should you buy?
Choose the Arahi 9 if you like HOKA's rocker and want stability that doesn't feel stiff, with a very durable outsole.

The Arahi 9 is 22 g lighter than the Adrenaline GTS 25. It has 2 mm more foam under the heel. Its drop is 8 mm against 10 mm. It costs £5 less at full price.

What's new in each
HOKA Arahi 9: Mainly a new engineered-mesh upper with more toe-box height, plus better wet grip and a later forefoot rocker; slightly less stack and a little heavier than the Arahi 8.
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.
