Need Help??? Gear identification!!
 

What kind of boots the guy from bottom left of the picture use????
thank`s for yor help

They look like some model of Merrell. This picture being a few years old they are good chances that this specific model isn't available. Right now one of the model that is favored by the SOF community seems to be the Sawtooth :

This could work as a replacement I guess.

Its an early 2000 Merrell Chameleon Ventilator. They don't make it anymore but try Ebay or just get the current Sawtooth or Chameleon.

I'll put my recommendation in for the Sawtooth. Good boots.
Mostly used them for backpacking (did the West Coast Trail in them, but probably should have gone with something waterproof), and they've been comfy.
