In reply to Removed User: Hi, I have exactly the same problem (broke the end of my fibula at end of Feb, have plate and 7 screws), and was thinking of posting to ask exactly the same question! I may be able to have the plate taken out next year but in the meantime I'm a bit worried about the winter too.
My ankle is more or less fine now and I've been hiking in the mountains and done a few ferrata, but wearing low-cut shoes. Tried my hiking boots the other day and managed a reasonable walk, but it's really uncomfortable over the screws after a while, and I haven't tried ski boots yet.
Would appreciate any ideas too. Let me know if you come up with a solution.
