The main advantage of these shoes is the fit. Too many athletic shoes are cut wide these days. But aren't most fit runners relatively thin with slightly narrow feet, or at least narrow heels? I'm always frustrated with how wide most shoes have gotten over the past 20 years. Back in 1960's the average width of men's shoes was "C" whereas now its "D" Fortunately these are cut in about a C+ width. They're particularly snug in the heel while a little wider, relatively, in the forefoot so your toes aren't crunched together too much. The length may be about 1/4 size short. Cushioning is good. Uppers are light...ideal for warmer climates. I'm sure they'd leak a fair amount in wet conditions, unless you get the Goretex model. Only drawback I've seen is that the sides of the sole are kinda wide and sharp, ie. without rounded edges, so they tend to catch and twist your foot sideways when steping on angled rocks.
