I like these shoes - super comfy, climb 5.8 with the laces tightened, can walk in, do Prusik WR and hike out all in one shoe, but the durability is an issue. Had one pair last 1.5 year, newer pair lasted 2 yrs and both are basically Ok for walking around the Smoke Bluffs but unsuitable for longer hiking now (sucked walking down from Chief summit in them on Monday). thinking of getting some Kayland Superguides, if anyone has any experience with the latter pls. comment. Or if newer Mt Masters (ie built in 2003 or 2004) have increased durability.
