I have 2 pairs of Viberg. Both are MTO, 1950 Service Boot Natural Aniline CXL 110 Last size 8 and 145 Oxford Icy Mocha Ripple sole 110 Last size 8. Yes It fit very comfortable, my feet are 26 cm height, 11 cm width.
Likewise, I had talk to Jason before and he provided me this.
310 last (called a sprung toe or turned up toe)
available. In E width (sz 6-13) and D-width (sz 3-9)
last. This last has a bit of a subtle bump at the toe in a D-width approx.
The 2045 last is very much the same as the 2040 but this last below is not as narrow or shallow.
2030 dress shoe style last.
Very shallow toe box area and is only available with E-width and the size range:
size 6 to 13.
110 last which has a flat feel to it with about E/EE width and
has a lower heel height and thus a lower arch in terms of support.
160 last which is our non-steel toe workboot last with a EE width and a higher heel height resulting in much better arch support. The higher heel makes this last way less popular since most people want lower heels like most of our boots. We have AA, B, D, EE and 4E widths available to make, EE is our standard width.
This information I had received on May 25 2013
The latest information that you can use for making a decision could be this one either. (I was looking in the Viberg's webstore and I would like to know the width of each last they are using on Viberg boondocker, Service boot black horsebutt, Service boot black scotch grain and Harness oxford. and this info are from Guy).
The 2030 is the narrowest and is a single E width. The 2045 is about a double E and has a munson style shape. The 110 is the widest of the three and the roundest.
sorry for my english guys, hope this help :)
