I own four pairs of Viberg shoes
1.) Viberg Boondocker not sure the Last, size 8.5 fit great
2.) Viberg Chukka cordovan 2030 Last size 8.5d fit ok bearable
3.)Black shell cordovan service boot 2030 last size 9 fit ok but like the 8.5 better
4.) Oxford (Sample Pattern), Natural Aniline CXL Roughout, Tan Lining, Leather Sole/Dovetail Heel, 2040 Last, No Box Toe, size 9 fit ok
So far the 8.5 fit best, the toe box including both sides of the ball of my foot is a little tight but not painful. No blisters have developed or joint pain.. Just wear thin socks.
On the other hand, my 2030 size 9.0 service boot fits much worse (both sides on the ball of my foot). It is a little too tight and I would need to wear moleskin or a great pair of socks to prevent blisters from devolving. I wore these boots for about 4 hours around he house and had to take them off due to the foot pain and hot spots around the ball of my foot.
I can still wear the 9.0d in size 2030 but would prefer a 8.5, hope this explanation assists you on your decision.
By the way if any of you are still on the fence http://www.manufactum.co.uk/viberg-shell-cordovan-boot-p1459459/ they look amazing in person. Pics included!
Thanks again. Your feet may be wider than mine. This makes me think that 8.5 might be the best choice for me. But I just don't know. I want to order these boots, but I have a bad feeling about this last. It is too much money to pit down with this much uncertainty.
