I do a lot of walking all over the U.S., and when I travel to Europe and New Zealand.  My quandary is always find a rugged, comfortable shoe for rocky trails and for city walking, and I keep coming back to Merrell Ventilators.  I have tried walking and running shoes with more cushioning, but the Merrells are more rugged, they breathe really well and they are comfortable in all types of terrain. They are heavy enough to give good stability on loose gravel trails, but not heavy like a classic hiking boot. This latest pair of Ventilators is the Moab 2 and it is a little tighter fit than the last pair of Ventilators I bought, not sure if they are made in a different factory, but they are stretching out some as I wear them around.
