These are comfy shoes. Like all Nike's, they run about a half size small. So if your a size ten in most shoes, you're going to want to get these in size 10.5.
The shoes look good, I bought the Rustic/Grand Purple-Dark Obsidian, and really like the earth tone-esque color way.
Like most Nike's, the manufacturing is not great. There are points where they really cheap out and instead of sewing an open seam down, they leave it exposed, giving it an incomplete finish. The laces are hard to push through the upper plastic lace holder at top of shoe.
All in all, they look great, but Nike 6.0's are not a high quality production shoe. For $84 bucks, they really need to finish all the details, sew down all open seams etc.
