I really wish we could get the same type of pictures for the rest of their lasts.
I like the look of the 2040. It looks like it's actually made for feet, though that last says 2E while the viberg site says single E.
Even though it's listed as EEE, it doesn't feel like EEE. I wear 2030s in 8.5 and I sized down to an 8 for the 110, and it feels quite snug. I should size the same across all lasts.
Viberg makes the 310 in either D or in E widths. In my experience it's not a particularly wide boot. Seems about normal, maybe slightly narrow actually.
But this points up the oddity to me of even talking about particular lasts corresponding to particular widths. I always just figure that the basic version of the last is its D width, and then if there are narrower or wider versions they get labeled C or E, etc. So, you can have lasts that are more narrow vs more wide, more shallow vs more volume, narrow heel vs wide heel, etc, but the basic one is always D. The 110 is a wide last because it's a wide last, not because it corresponds to some objective measurement of widths.
Red Wing's Iron Ranger to me is a long and very narrow last, but it's basic model is still a D, and it's so-called EE is about as wide as my old Chippewa's in their D version, but it's still a EE for IR's. And White's Semi-Dress last has any number of versions from something like BBB to FF; you wouldn't identify the Semi-Dress as any particular width. It just happens that Viberg doesn't have a wide range of widths for each last, so we've gotten into the habit of giving them widths, but we can easily imagine them making a EE version of the 2030, or a C version of the 110, etc. As far as I know, the only Viberg last that does have more than one width is the 310 (though I may be wrong about that, there may be others), but any of the lasts could.
I bought these from TZ laces - originally I ordered through Amazon - then ordered from TZ laces directly at the time they had these 3mm laces besides the regular 5mm laces...I was thrilled as I knew these would work with smaller eyelets...of course it turns out they had them by mistake and not part of the regular line so I ordered all the colors I could. You can check the site http://www.tzlaces.com/ and see what they have - I have the 5mm also and they are nice. If I have an extra pair of these I will let you know as they sent me a ton of free stuff with my order.
Edit- Seems they still have some choices available - under flat laces - 3mm
