This anti-fatiuge thing is so good!! They're almost as comfortable as a pair of sneakers! I had to walk through deep water more than once so I know they're waterproof.I was worried after reading reviews about them falling apart but they are holding up. I've only had them a few months so I don't know how long they'll last but I suspect years (couldn't wait years before I wrote a review so I'm giving 4 stars.)What I didn't like is that one of the inner soles was too big and I had to cut it to make it fit properly - this I botched - I would hope the makers read reviews and I don't have to worry about above mentioned complaints happening, so uneven inner soles won't happen to anyone else.Whenever this pair becomes worn out I will most definitely be buying another pair of these Timberland boots! Did I mention how comfortable they are? And believe me I have been working these boots hard! The metal I've been working with has cut them up good and deep. And they still are waterproof! Money well spent!
