I work in a rough industry where generally you need very tough boots like red wings or thorogoods. I’ve used a ton over the years and usually after 3-6 months the boots are destroyed or riddled with holes from glycol or oil and other chemicals.I’m a commercial/industrial HVAC installer and can say that these are by far the most comfortable boots I’ve worn which made me nervous at first. I’ve always been taught good boots should be uncomfortable for a while until they’re broken in. These almost have no break in period at all. Only break in I had was the heel on the left boot rubbed a little bit for about a week and ever since then they’re perfect.Also was worried about ripping the pull tabs off but as of now there is no tearing, leather looks good but I need to clean and condition them soon. Soles still have so much tread on them. The soles on these boots are like an almost transparent material seem very durable so far.They have also not stretched out like other boots I’ve had that are “slip on”. They’re nice and snug around the ankle.****one thing to note, these are the model with the toe cap protector as I constantly have to kneel down or crawl around under equipment so it’s necessity for me.I’ll be buying another pear of these boots and possibly the mock toe model as well to see how they hold up.
