The Quest 4D is hands down the best boot I've ever had on my feet. I think I said "Wow" before I had them tied. They are light and comfortable immediately. The upper is flexible, and the lacing makes the boot an instant perfect fit. I have a W foot, and all I had to do was let the laces out; no break-in required. The sole and heel are more rigid, so once you are laced in you have plenty of support. I read a review that somebody had trouble with traction, but I have no idea what he was talking about; these grip as well as any boot I've had. Yesterday we went out to dinner and I put on some cargo pants instead of slacks, just so I could wear the boots. Definitely my new favorite footwear!
