Dissapointing boots.
This is my first pair of Carhartt boots. It hasn't even been half a year and the soles are already worn out. I slide right off when I'm climbing chutes and slides. Another odd thing is that both boots developed a squeaking sound when I walk. It would be more understanding if only one boot made noise due to some random factor, but to have both do it doesn't instill confidence in my overall impression of these boots.

My go to boot
These boots lasted me a year of 12+ hour days and were amazingly comfortable the entire time. The average life span of my footwear is 6-8 months. Ordering a new pair as soon as I'm done writing this.

work boots that I always wear
I have worked in the auto repair for 20 plus years and as you can imagine, I have owned many work boots. These Carhartt boots HANDS DOWN best I have ever owned. But it is not a surprise due to everything else I have purchased is WONDERFUL. Hell my Family & walk at the local YMCA and I wear my work boots.
Thank you for such a great product

Bought a pair in December 2016 after 4 months had to exchange due to defect. Second pair lasted about 8 months, uneven wear on the soles caused a hole to appear and allow water in boot. Own a lot of Carhartt merchandise, these boots are by far the lowest quality item I've purchased.
