I took a chance on these, wondering about the famous "air" soles, and also wasn't sure about sizing. I usually wear a 13, but I read these fit somewhat large. They do, the 12 is a good fit for me, maybe the square toes make a bit of a difference. They are very nice boots, the leather is soft, but sturdy, they seem to be a strong well built shoe. Nice finish, a pebbling on the leather, with black darkened soles and stitching. They are very comfortable right out of the box, I'm sure they'll be even nicer after a week or so of wear. The soles give a nice, light spring to your step, our kitchen is tiled, they feel great on that, so they should do well on the cement and tile floors I spend time on at work. I was also concerned about the weight of the boots, I wear a Clarks Cotrell chukka boot, they are very light, but the soles are thin, and not as comfortable at the end of the day as I would like. These are not at all heavy on my feet, they are a sturdier shoe than the Clarks, and will probably take more abuse and wear.  think these will be better after a long day on my feet. I may have to order the brown Sussex, to replace the Clarks. I hope they last a year or more, time will tell.
