Jcusey, the bevelled waist pictures are very helpful, especially the Vass. I presume the Vass shoe in your picture is the Oxford medallion.
Yes, it is.
Other than the one image on Amesbury's waist I have never seen any shoes or pictures of shoes with "fiddle" waist. I made it a point to look for them during my recent visit to London. I checked out JL Paris (Jermyn Street), EG, C&J, Cleverley, Foster & Son and even Berluti but with no luck. Foster & Son and Cleverley said that they could do it (bespoke) but could not show me any samples. Similar pictures depicting fiddle waist shoes would be much appreciated.
Something as pronounced as that Amesbury shoe? I've never seen it on any RTW shoe. In fact, I've looked throught the bespoke shoes on Jun Kuwana's website, on the Cleverley website, and on the John Lobb St. James website, and I can't find anything remotely comparable. The only footwear with as pronounced a bowing on the sole at the waist that I know of is the cowboy boot, and most reputable RTW and custom bootmakers will be able to do something like that.
Also, how does fiddle waist compare to bevelled waist in terms of skill level and degree of difficulty to make them. Wouldn't the fiddle waist necessitate a steeper arch along the waist? If so, how would it affect the fit and comfort?
I would think that it would require a steeper arch. That's why the heel is so high on that Amesbury shoe and why you see it on cowboy boots, with their two- or two-and-a-half inch heels. Frankly, the fit and the comfort of the shoe is likely much more effected by the higher heel than it is by the bowing of the waist. Lucchese makes some fine boots, but you're not going to convince me that the level craftsmanship that goes into them is equivalent to the level of craftsmanship that goes into, say, a Vass shoe. In other words, doing a proper fiddle waist may require some specialized skills, but I don't think that you have to be the best of the best to pull it off.
