Need some (real) men advice

I made a schoolboy mistake to buy a pair of Florsheim shoes many years ago (2016, I think). I don't wear it often, so it is always kept in its box with a cedar wood shoe-tree and it is in really pristine condition.

Recently changed new job, and felt like wearing it into office on alternate days. Realized that the soles have separated.

I know my Florsheims probably don't meet many (real) men (high) standard in here, but I hope to fix its soles and use it as a pair of alternate beaters.

Question:
1) What should I do with the soles? Should I ask a cobbler to stitch it? And once it is stitched, that is basically the end of the shoe, right? Like it'll ruin the construction of a shoe.

2) And when stitching, the cobbler should not hard-press the shoe, so that it the top part of the shoe does not crease, right?

3) I hear from P.Lal Store that there is a professional cobbler shop in Bangsar South that has better craftworks compared to street cobblers? What do you guys think? Any recommendable professional cobblers?

4) What other courses of action would you guys take, if in my position? The Florsheims are still really good, except for the splitting soles.
