Hi,
I've used Diamond Hard Varathane on all my C.L. shoes, to protect the red soles, and it does help with this, as long as you use several coats, and wait a week or so before wearing them so the varathane can harden. It seems to work better on shoes that don't bend a lot when you walk--meaning the soles don't flex all the time. The varathane can crack on those styles--so it works best on platforms--and Simples, for some reason. It does wear off with time, so you have to re-apply. Yes,this is for the obsessive types only--and I am one of them!
The arch of the shoe does not seem to bend--so it should be okay.
If you want to protect the signature, be sure to test a small area first--I would feel so awful if someone smeared their signed shoes!!! I DO NOT HAVE SIGNED SHOES, AND HAVE NOT TESTED THIS! Please wait a few days post-signing to let the ink dry well, then try coating a small area with the Varathane to make sure there is no smearing before you proceed.
Let me know if you have questions, and I'll do my best to help.
