Zachary J.wrote a review of The North Face Single-Track II Trail Running Shoe - Men's on June 1, 2013
I've worn North Face now for about four years. While I'm sure there might be better shoes out there, I have been happy with TNF. I recently ran a 50k and 50 mile race with the Single Track II with no issues. My only complaint would be the wear on the soles. Oh, and I'm not a big fan of the color choices currently but that is not really a big deal to me.
Fyi, I live in San Diego and normally run rocky, slick trails. These shoes work well in these conditions.
