I purchased these boots in the summer of 2011. They have held up extremely well over the almost 4 years that I have worn them. As an automotive tech, my boots are constantly exposed to oils and other chemicals. They are also on a concrete floor a majority of the time. The soles were the only thing to wear out on the boots as the leather, stitching, trim, etc. are in excellent shape. I would HIGHLY recommend these boots as they are superior to any other brand boot I have purchased and worn in my life. 

I love these boots these were the only boots that at the end of a long work day my feet didn't hurt one bit and especially for being flat footed that's a big plus I got them in August 2013 and going for my second pair now I probably wore them longer then I should have cuz the tread is practically gone but they still did the job and still no pain on my feet

I usually burn through boots in a year, Ive tried all the high-end work boots and nothing works as well for me as the redback boots. Im an automotive tech by trade and on my feet most if not, all day. I think this is a comfortable, quality, well- built boot that will serve you well, also more slip-resistant than most.
