John Holmes wrote a review of Merrell Perimeter GTX Backpacking Boot - Men's on December 10, 2009
Pros: One of the best Vibram soles I've ever seen. Super deep lugs and very aggressive heel cut (for braking on the downhills). Love the leather uppers, the lacing works well, ankle collar is super comfy, and good forefoot cushion.
Cons: Didn't grip my heel securely enough. I seem to have a narrow heel so this is not unusual for me.
Final: I wanted to love it, but had to return. The return was totally painless. Love doing business with Backcountry.
