My name is Ian, and I have big wide feet...13 d to eeee depending on maker.
Right now my Lowa Tibet LL are ok, working with a cobbler to fight some spots. There are many different varieties of the Tibet, the LL (leather lined) fits wide.
They replaced meindl lightweights which fit fell, however they didn't give me enough support and contributed to my blown out feet (the bigger issue I've been fighting for 3 years).
I wear Merrell Moab low WIDE daily and they are the best so far, they also make an ankle version.
Danner Gavre 4e (same as Gila, just cheaper no optifade) started ok, but then said no to me...
Tried on some vasque breeze 2.0 gtx and they where close, they make a wide I haven't been able to try yet.
I have some hi-tec altitude iv wp in d and 2e waiting to try on, time will tell
Also I found this recently
Hiking Boots For Wide, Flat, Narrow Feet 2016 | Boot Bomb
Lastly, a blundstone rep,told me once try on two or three pair of the same boot if you can, no two are the same if made from leather.
My current quest is more of a mid to light hiker and I'm complicated by orthotics.
Hope this helps
Ian
