I was so amazed after trying these boots on...that I immediately bought a second pair. The Caterpillar 2nd Shift 6" Boot is comfortable - my feet don't tire in them, even with a full 10 hour shift on my feet. These boots didn't require any break-in time at all.

I've experienced no chaffing or blisters, there's wiggle room for the toes, room for thick socks, the laces are long enough to lace to the top of the boot and double-knot it. The soles haven't marked any regular finished wood/concrete/vinyl flooring. The padding on the tongue and around the uppers (above the ankle) is sufficient and comfortable.

I'm extremely pleased with these boots!
