If it's not going to put you out too much, I'd seriously consider the new skates. I mean 10 years is a pretty darn good run. With my last pair of skates, the first signs of them going were the little things, rivets and eyelets popping, and stuff started rubbing as the liner and tongue wore away, etc. I nursed the skates along for a year or so until a broken holder forced my hand. Honestly, I probably should have gotten new skates earlier, because over time, I'd dropped over $100 on rivets and stuff just nursing them along. I could have put that money towards the new skates.
As for it being worth it, well, that's a question only you can answer. But you're only 45. I'm the same vintage as you and play against guys who are in their late 50's who can still skate circles around people 30 years their junior. So, you probably have at least 10 good years in you of playing.
Take a look at your skates now. Really look at them, every seam, every stitch, etc. How much life do you think they still have? And how much do you think you'll have to invest to keep them going vs just getting new skates?
