In reply to Matej:
You could speak to Adventure Peaks. I recently ordered a pair of La Sportiva G2s online. I traced the outlines of both feet ( in the sock combo which I would be wearing), onto squared paper, measured the maximum length and width dimensions and put a scale up the side of the paper, scanned and emailed the images at true scale. A short discussion by email over sizing and how to get the boots to where I live ( outside Europe). Boots turned up and fitted very well. No issues once broken in and adjusted to my feet
