Lugged vibram sole, stiff for backpacking, decent ankle support. Comfortable and fairly light for what they are.
There is enough stitching to worry about durability, but I applied some seam sealer to protect the threads against abrasion (bushwhacking/cross-country/scree). I don't expect them to last as long as full-grain leather boots, but they don't weigh as much either.
My feet measure 9.5 U
