Why not replace them with a new pair of SP-Terris? Within the past year, I returned to skating after a ~17-year hiatus. I used to skate in Harlicks, but when I returned, I ordered Jacksons on the recommendation of a skate pro. They have never been as comfortable as my old Harlicks, and I've had problems with durability of the soles (2 sets of soles now in just over a year) and customer service.
If you think you're serious about returning, it's worth investing in a pair that you'll be happy with; otherwise, they have the potential to turn into a recurrent source of frustration. Get a pair that will carry through if you intend to get back to doing doubles. Things will already feel different for you as a returnee; you don't need an additional source of frustration.
