"This shoe runs a bit small, I ordered a size up and it fits perfectly. Only problem is, when you order up, the shoe gets bigger and it hits me at the thickest part of my legs. So the boots make me look like I have huge calves. As for comfort, I've only tried them on to see the sizing, I haven't worn them out yet so I'm not sure how comfy they'd be if I wore them a whole day."
