I wear the 606 Men's 6-inch Boot at work, and since I spend a lot of time standing on concrete, I really like the padding that the thick sole provides. They've saved my toes a few times too! I still have my first pair, which are about seven years old now.
The soft toe boots are easier to ride in than the safety toe boots, but some shifter adjustment helped with riding with the steel toe boots on.
I like them and think they are very comfortable and durable.
