Query: poor workmanship

the left boot has completely fallen apart. throughout the entire circumference where the leather meets rubber, a complete separation has occurred. although I've owned the boots for over four years, i didn't regularly wear them. in fact, i exclusively wore the boots while i was camping or while up in the mountains. in all, i probably wore them a total of 30 times (that's being generous) and i never did anything more strenuous than walk or sit. my wife owns a pair of canadian made caribous, which she has worn for 15 years and they still look brand new! when not wearing the boots, they stayed in a cool, dry closet. to say I was disappointed to see the seam break apart while shoveling three feet of snow is an understatement. i also found the lacing system to be ineffectual and the heel strap equally ineffective. i would not recommend this boot.
