Our Verdict
Altra Torin 8
Altra Torin 9
The Altra Torin 8 is a better choice than the Altra Torin 9 if you want more cushioning and comfort for daily training. The Torin 9 sits lower with a firmer midsole, giving it a more stable feel and a closer connection to the road. Otherwise, they're very similar.

A nice update, but, really, I would challenge anyone to be able to notice a .3mm or .2 mm disparity on the offset! Maybe, just maybe, the companies are finally addressing the every day runner requests for firmer, lower drop offerings. Be careful what you wish for! But, more and more and more runners seem fed up with max midsole stack height. And white running shoes! Did I mention the preoccupation with white/light color offerings in running shoes?! (“Aren’t these just going to show dirt/get dirty??!!”) Groan!
