My favorite trail shoe by far.  This is the 2nd set i've picked up and will be sad when they discontinue this line.  Overall durability is fantastic of both the material and soles (have >600mi of running on first set) and excellent traction.  Be warned that this shoe is fairly narrow and runs a tad small.  There are also two 10.5 (US) sizes.  REI sells the men's 10.5 as a 43.5 euro which fits closer to a men's 10, and the euro 44 is considered a "10.5+" which is the more accurate fit IMO.
