Hello, I purchased these boots back around March of this year. I'm a brewer and luckily I'm not around much water or other harsh chemicals. After a week of usage I notice one of the boots was making a noise like if it's getting air every time I walked. The next week I noticed the sole was coming apart from the leather. I went back to the store I purchased them and they exchanged them for a new pair, they thought it might've been a defect from the factory. Second pair comes in no noise after several weeks of usage but I notice again the sole was coming out on the back heel. Went to the store again they told me they don't do exchange only one time courtesy but they will work with me. At that point I was getting very mad that I spent a lot of money on a pair of boots that didn't last me very long. After all of this I got me a pair of stitched sole to avoid the problem again. I wish they would make those boots with a better quality glue or what ever they use.
