I restore old vehicles so I'm on a concrete floor in a shop all day and these boots are super comfortable. The sole design is really good for were I use them. Other boots I've had in the past had more of a hiking style tread and I didn't know how poor that was until I tried the Timberland Pro Bosshog. Their tread is like a performance car tire, which is perfect on concrete and asphalt. Their oil and slip resistance is pretty impressive. The waterproof, composite safety toe, electrical and puncture resistance are more than appreciated. Among these great attributes, the anti-fatigue technology is better than advertised. A+
