It started with a pair of Service Boots in a 2040 last, I wear them all the time.
Now I want a pair of the Derbys. Viberg has my size but it is in the 2045 last. I really like the shape of the 2040 with the unstructured toe. How significant is the increased roundness of 2045 last with the partially structured toe? Should I wait until they have the Derbys in a narrower model?
