I have always bought MH High Riders and needed the wide calf. I find the regular ones okay - but they are only just okay, and the zips take more stick if you are using them regularly and they are only just a fit. I don't have wide legs either - in other boots I buy regular calf width. But experience of the MH boots in the past left me buying the wide fitting. I used to get the short height too, but I'm not even sure they still do them. I think in some ways zipped long boots can be harder to get over jodhs or breeches than skinny jeans! Of course it depends on the material your jodhs are made from, I know some are quite thin aren't they. I bought the Shires Moretta long riding boots in regular and they are fine and I also have Shires Pamina ones but got wide in those because I wanted something easy on and off.(they have a little bit of stretch in the back panel too) which are comfortable. It's really personal preference though, if you're patient (I am not) and feel that you'll be okay zipping them up time and time again over your jodhs then go for the regular. I don't think there is that much difference - but I think the little bit of extra can help prolong the zip life. Over the years I have had probably along the lines of 8 pairs of MH boots. Of those all bar one the zips died on me!
eBay have some lovely looking ones but they are wide.
