I've had a pair for about 6months or more. I have found them to be comfortable and supportive aswell as reasonably light at the same time.
Getting towards the end of their life im finding that they're starting to come apart on the bottom of the shoe. The rubber in the mid-foot has worn away completely so often squeeks and stuff when i run on road or boardwalk and stuff as the plastic (or whatever is under the rubber) hits the ground. The upper middle of the shoe has worn away alot and I have gotten many rocks stuck in the holes in the bottom of the shoe (holes that are meant to be there that is!) some rocks have pushed through into my foot which is abit annoying and the bottom of the shoe is really weak.
In conclusion, great shoe, don't wear it past the expirey date though!
Good Luck
