My feet pronate (roll inwards) and I have inserts to correct this for RTW shoes.The shoes Cleverley make for me (inc. those pictured) have a built-in raised section under the arch which does the same job as the insert but without altering the fit. It works very well.
I posted a photo of my 337 upthread. My first luxury watch and I love it. Spent a *long* time looking and musing before pulling the trigger. Went for the 337 because of the smaller size (and didn't like the magnified date on the 40mm Luminors). Would have preferred the 338, but couldn't find one.
