I've bought a pair of these 10 years ago and used them for 4 years then off and on again for the last 6. I'm finally replacing them...with another pair. I can't break away from them, they're comfy I walked in them all day when I was using them. Been in the snow/water/heat/mud...just lace tightly and no problem. Only recently the liner and zipper starting falling apart but they lived well past what I expected. I'm very happy with these.
