Nick Mitchellwrote a review of New Balance Leadville v3 Trail Running Shoe - Men's on April 15, 2017
Familiarity: I've used it several times
Fit: True to size
I suppose I need to say this in advance: I wear a size 15 2E (Backcountry does not stock this size; I ordered directly from New Balance), so there really aren't many choices for me. So perhaps I'm excited simply to have anything... Yes, there's some of that, but this is a pretty great shoe so far.
It looks great (not the ugly bright blue; Backcountry, stock the Black with neon trim, it's substantially more appealing). It has a decent amount of lateral stability, as one dances around rocks -- though not as good, here, as the Montrail Sierravada. It's overall pretty nimble. The Vibram sole is quite a bit better at adhesion than that of the Montrail. It dries rapidly as one sloshes through much and waterways. The Montrail, while available in size 15, is not available in 2E. And, anyway, Columbia bought them out, and seem to have discontinued the Sierravada.
Another shoe option also available in a 15 2E is the Brooks Beast. While trail running, there is a night and day difference between the two, in favor of the Leadville. The Beast leaves one with little trail confidence: it's not very nimble, and has very poor lateral stability when dancing on rocks. And much lower rock adhesion.
