it is ok for the first 3-4 hours and then I feel it along my pinky toe area. Perhaps as the day goes by and my feet get a bit larger it results in the fit getting tighter?
Your feet swell over the corse of the day, some peoples feet more than others. It is most likely if it bugs you more later in the day. Try measuring your feet early and late to see if this is happening.
I get that a little bit too, though only in the right foot (which is interesting because my left foot is bigger). The nice thing about CXL is that it is softer and more supple. I suspect it will get better once the shoe breaks in. I don't know for sure, but I think some neats foot oil and leather conditioner (Saphir or Venetian) will keep it nice and soft (hence easier to stretch).
