These boots are very comfortable.  They take about a week to break in while wearing them to work or around the house on the weekends.  Once they are loosened up a bit, they are extremely comfortable.  Build quality is amazing, but you would expect it to be for what they cost.  I am more of a size 9, but the 9s I ordered cause some pain in my right foot so I ordered a 9.5.  It fits better, but on extreme inclines, I feel a tiny bit of heel slop, which can be fixed.  Overall, I love these boots.
