My all time favourite rocky terrain shoe
I get my exercise on The Billy Goat Trail along the Potomac River's Mather Gorge in Maryland. The terrain is almost all rock, with at least distinct types in the two miles of the trail.
It takes stickiness to hold to the flat surfaces, stability to balance on the angles, rigidity to step on the points, and edges stiff enough for the little lips and nubs.
This shoe has all four, and is comfortable on the runs through the woods afterwards.
I'm on my third pair, with the fourth in the box, and am distressed that they're getting hard to find.
They do fit small, but that's what I need.
