I'm retired in my 60's, only wear these boots one or two times a week and go for weeks in the winter months with out wearing them.  I purchased the boots 8 months ago (11/14), within a month or so the laces broke, now at month eight (7/15) I find the left boot is coming unstitched at the heal where the heal leather meets the rubber sole.  The both boots are coming unstitched where the heal leather meets the back ankle padding.  I don't wear them in water, I don't hunt with them, I've been building a 2nd story deck and doing light yard work.  Most likely I have less than 100 hours of wear on them, very disappointed!
