As always, choose a size smaller than what you normally wear. Mainly because the skin stretches, but these sizes are just too big. I have bought them a few times over the years after 1 pair has worn out. I normally wear a size 10.5 so chose a size 10, very nervous about going down a whole size but now I really wish I had. I recommend when the shoes are off, tightening the leather laces and then putting them on. Because it is not easy to get the desired tightness when wearing leather laces. Also, as I said, I've bought them a couple of times and I'll say that this price is the highest ever. These moccasins should realistically be around $45-$55, $70 seems like a lot, but they are very good quality.
