What can be done to fix damaged/split cuffs on shoes?

[MajorLance]

Greetings everyone,
I have purchased a pair of recently-recrafted Alden 990s. The shoes are in great condition for the fair price I paid, but I was wondering what to do about the damaged/split cuffs on both of the shoes (perhaps caused by the previous owner not using a shoehorn). What can--and should--a cobbler do (to at least prevent it from getting worse)?

Thanks in advance for any help!
