Ariat squaretoe workhog here. Most comfortable boots Ive ever had. Absolutely no break in period, feels great right out of the box. No aftermarket insoles needed.
Ive tried on a lot of different work boots and the Ariats are the best for me that Ive found yet. I wear them practically everyday, doing all sorts of work, in all sorts of weather.
I even wear them for good. I usually buy a new pair every year for good boots and take the pair from the year before and start wearing them everyday for work.
