I really liked my Asics. I used 3 generations of Enduro model. I liked the fit, narrow sole, and fairly strong platform. When I had a little trouble with the fit on the last model I tried switching and got a pair of Columbia Switchback 2's. This is where the story gets weird for me. I hated them. The sole seemed too wide, the platform too soft, they felt "floppy" after the Asics. But, I decided to wear out the shoes in my closet and started wearing them again. As much as I hate them, my feet seem to love them. I never had much blistering or foot pain (I use Injinji), but with these I had none. Maybe it's the "minimalist" thing. Less shoe better feet?
(I generally wear shoes from SportsMart or SportsChalet, that class of place. I shoot for $50-60 on sale, and that seems to work out fine for me. I can't wait for more minimalist options to creep down-market!)
Update: in M8.5, the Asics are 12 oz each, the Columbias 10 oz.
