Puppy is right, don't think your Nike liner is like your old one and will give a little. It won't. I learned the hard way in my Kaijus and, after four hours, it was pretty clear that I needed to loosen them.
The insoles are terrible in them, especially if you have a high arch. Get the best replacement you can afford, preferably custom.
Next, be careful about doing the inner laces too tight, that flywire wrap has very little give, it's easy to over tighten.
Actually I have fallin aches, I tried them out for the first time yesterday and on the mountain they felt great. It was a major difference when I was actually using them on the mountain. I had on thin socks and didn't feel any discomfort. They are packing out nicely!!!
