I found this boot very comfortable and well fitted right out of the box. I did experience a minor discomfort for a couple of days on my left ankle area. What I believe caused the issue was the shoelace loop seam located there. I found that by making sure the boot tongue was spread out would alleviate the discomfort until the boot fully broke in which happened quickly. The black mark on my left boot (see photo) is from my shifter on my Harley. Im wearing the boots for work which involves being outside in Arizona mountain terrain and so far these have done a great job.
