You probably should have gotten a wider boot.
Try not tightening the inner lace too much. If that doesn't work, it might be weird, but you could try using 2 lace locks on each boot. You should have an extra set with the spare laces, so trying using one at the toes.
I didn't really have any problem with the boots until I started riding with it. It was really comfortable when I wore it at the store and home.
I think I got it all sorted now. The issue was solved by lace locking the toe area of the laces, so they stay loose and also lowering the insole at the toe area helped as well.
