Very comfortable
Size: 9.5, Color: Black/Cool Grey
Awesome shoe, very comfortable. As a trail shoe it is a little firmer than a running sneaker as expected. The unexpected was the comfort the shoe provided. Nice looking as well.
I've been wearing against most of my life. Always find myself coming back to them when I tried other brands.
Size consistency has always been near perfect.

Excellent support and comfort.
Size: 12, Color: Black/Carrier Grey
A comfortable, lightweight shoe, with a nice heal cushion that gives slightly but not mushy or squishy. Very breathable. A solid choice for everyday sidewalks and trails.
