That actually sounds a lot like one of Cleverley's signature shoes.
This elasticated slip-on was old Mr Cleverley's favourite style. If he didn't invent it, at least he refined it and created numerous variations (one even with faux-laces). He believed it to be the shoe style to give the perfect fit. For those with the current Cleverley catalogue on hand, they feature versions with the V-cut and without. Without: page 2, picture 1, 6, 52. With V-cut: picture 14, 15, 41, 45, 76. (I'm afraid, I don't have a scanner; so all of you who haven't got a copy, will have to contact Cleverley, unless someone with a scanner and a catalogue can add the pictures.) They all feature the leather strips. Maybe T4phage can tell us, whether or not this style makes the ideal fitting shoe as he has at least one, maybe even more pairs of that side elasticated style.
Which current catalogue? Â The latest one I have from this year is a blue booklet with Mr. Cleverley on the front examining a perf captoe oxford. As for fit, I did not like any of the RTW side elastic that they had, the forefoot narrowed a bit too quickly for my little toe, and a half size bigger was too big. Now, as for bespoke, that is something else entirely. Â Mine fits like a glove, extremely comfortable and extremely elegant. Â I have the plain side elastics with an apron front (I now have 3 machine stitched - I find it a cleaner/sleeker look than the handsewns, and one handsewn - a bit more casual). I did not opt for the leather strips covering the elastic, I did not like the look, too busy. Â But from what I remember, the RTW's did have the leather strips.
