Great fit, grip, breathable, light, have other brands but will always wear these because they are so comfortable and 24 hours until feet get tired. I am an 8, but the 9 fit, ie 40.5. (my mom took the size that were too smalll for me. (Backcountry emailed right awat ro verify not an exchange ir error) I have narrow heals, wide forefront.
I used to wear patagonia drifters but no longer make, tried some salomons, speedcross too tight in tows, extremely sweaty since waterproof but great cushion and support, ultra low fits great but cushion and support inferior to la sportive, brooks fit way off, merrill toes too narrow and no cushion or arch is wrong for me, keen heels too big and arch feels way off but very cushy.
No heel loop and toungue was weird at first, fine now, may have been squashed. Less odorous then other shoes.
Buying another pair and am going to try and stock up in case discontinued
