I've given up on my Bonts after the realisation that my 2nd & 3rd toes are longer than my big toe - this meant that whilst the 44.5 wide was too long for my foot generally, my 2nd & 3rd toes touch the end of the shoe uncomfortable, and in a manner that I don't believe molding would sort.
The Bont shape is great if you have 'normal' feet, but having reverted to my Northwaves it seems the more normal, pointier shoe design is probably better for my freaky toes.
I'm going to try Sidi Mega again...
(and as a side-note, if anyone wants a set of Vaypor Premium in 44.5 wide I now have a little-used set for sale!)
It takes some work to shape the Bont's to most feet.
I had the same little problem.
Solved it by shaping and taping some felt (the type you put under the chair legs to save the delicate floors) over my 2nd and 3rd toes, and over my bunions.
Then I put 2 pair of socks on.
Did the usual molding process. That took care of the toes problem.
For the volume, I put my Specialized BG insoles, and use some thick cush socks.
The fit is now very good. Not perfect, but fine for me. I learned how to live with, and use these special shoes.
