Thanks guys - I appreciate that you've taken the time to reply.
Was actually referring to the suit in the picture rather than the shoes, about how they're quite slim. I definitely want to go for a pair of Oxfords, or something similar.
Re the name of the section near the tongue, was actually referring to the 'instep height' lol presumably a lower height here gives the illusion of a sleeker shoe?
I think I also need to research 'last' as well
