Does anyone here specify, or for the resellers here have a customer who specifies, different sizes for left and right feet? I'm still having bad problems with heel slip on my left foot which, in fairness to EG, I get with all my shoes except for the one bespoke pair of Cleverleys that I own. My EGs are size 6.5D (UK) on the 888 last.
EG have been great in trying to help, they sent my shoes back to the factory to fit an extra piece of leather to the inside of the left heel but it was too thin for the purpose. I've now been experimenting with some very cheap leather that I ordered from ebay to add extra layers of leather to the inside of the left heel myself. I've stuck bits of the ebay leather that I've cut to size on top of the leather that EG put in using double-sided sticky tape(*). To get rid of my heel slip I seem to need two layers of my 1.6mm thick ebay leather on top of the thinner extra piece of leather that EG fitted in the factory. In total I'm building forward the inside of the back of the left shoe by about 3.5mm to get the left heel cup to make the same degree of contact with the back of my left heel as the right shoe does in its unmodified state.
From a bit of googling on shoe sizes it looks as if the length difference between a size 6 and 6.5 (UK) is about 5mm and not all of that would come off the back of the shoe, some would be a shortening of the toe box, so my guess is that going down to a size 6 would probably pull the back of the shoe about 3mm towards the back of my foot and maybe a bit more.
I think a size 6D would probably be too narrow for my left foot. Even on the 6.5D my left shoe needed breaking in before it stopped feeling as if it was squeezing my foot but presumably I can address that issue by going up a width on the left foot so I end up with a 6C on my left foot and a 6.5D on my right.
I can't imagine that having odd sized shoes as described above is going to look weird, in fact I suspect it wouldn't be noticeable at all. With a 5mm difference in length where at least 3mm of the difference is at the heel and so hidden underneath my trousers a 2mm difference in the length of the toe cap should be unnoticeable in real life, especially when people rarely stand with their feet exactly lined up with each other unless on military parade, and I'm guessing that widthwise a 6C and a 6.5D will be the same width to within perhaps a 1mm difference so even less noticeable than any length difference.
The above is for future orders of course, I'll need to either live with the heel slip or get the back of the heel built out more aggressively on my existing pair to fix that problem.
Any thoughts or first-hand experiences regarding different sized shoes?
(*) My pieces are stuck in with sticky tape, the EG piece is sewed and glued.
