I just ordered my 3rd pair of these.  I really like the shoe because it has a stiff midsole which offers a lot of support and they just feel good on me climbing around the mountains of Arizona.  I've had no problems with the lacing system except in a pair of XT Wings which is a slightly cheaper model.  I enjoy the simplicity of the lacing system and just being able to slide the tensioner into place.  These shoes last me a little over a year but I hike on pretty rough terrain - lots of rocks - and probably log about 20 miles a week on them.  I wished they lasted a little longer but that hasn't kept me from buying another new pair each time the old one wears out but it's why I took off a star.  The good part about buying a new pair is you get to pick some different colors!
