guys, after wearing my boots a few times, I decided they are simply too small. Went to the store, picked up a set of 43s. Now that Iv'e put the 43s on, I think these boots run TTS. The 10s, which I wear in AE, fit just like most 10s I wear. Perhaps a bit loose around the ankle, but overall the fit is much better. I'm selling my 42s in dark chocolate if anybody wants them.
