I have spent so much time searching for a comfortable work boot. 100's of dollars spent searching for that right fit and countless returns of disappointment. THESE BOOTS ROCK!!!! I am beyond happy with these boots. As far as the fit goes , if you wear a size 11 get a size 11 . They fit as expected .I work as a high voltage electrician and on the rail road with countless trip hazards . The weight is great ! The style is great ! The support is great!!! I have read some reviews about small toe boxes on these pffffft I think those people are crazy .... or they just have odd shaped feet and probably need to wear sketcher shape ups to work lol. These boots boots HAVE a great toe box!!! And I have plantar fasciitis to top it off and don't have a problem being on my feet all day in these boots. So there is a small con...... they don't breath as well as some boots do. They kinda remind me of hiking boots in the breathing sense. throw some powder in your socks and quit whining.... BUY these boots, you wont regret it .Ok, here's an update ..... the boots are holding up well and are still very comfortable. The only things is THEY DO NOT BREATH!!!! My feet are soaked at the end of an 8 hour shift. I am thinking of punching some grommit holes into them to have some sort of air flow.
