I think the first thing is to see that 4E has a hope of being wide enough.
I did this from a pdf template that I downloaded and printed ( can I find the link ? nooooo....!
)
Once I'd established that this was a possible runner I used the web for nearby shoe shops that might have what I needed.
Well, that was a waste of time !
Next step ( after a couple of weeks of reflection/plucking up courage ) was to phone the distributor of one brand that I had found.
I was put through to somebody who put me through to somebody - well you know - and at the end of it I was speaking to the MD
who said "we stock them and we sell them but nobody needs them so the retail trade dont want to know about them.....Why dont you come up to us & we will sell them to you if they fit."
3 days and 80 miles later I was there! I bought myself to foot heaven. Every morning, when I put on the shoes, I think of that day.
The shoes that I have are made by Propet ( a Canadian company ) and might have some drawbacks - no brown only buckskin etc - but whadda I care, they fit ).
Later I got a pair of Forester boots made by a company called Whelan in Ireland. They are 6E ( I use insoles in them ) They are great and really made very well. ( For me these are the key to life as I have to tramp the hills a lot. )
So far as cost go I think the shoes were around £50 and the boots £80. I'm very lucky that I can consider this a small price to pay for foot heaven.
