Long term Lake Winter Cycling Shoe review - MXZ302

I'm now 6 seasons into the Lake winter cycling shoes model MXZ302.  That's long enough to say long term.

And what do I have update?  Not much.  Prior comments stand.  What can one expect for maintenance over that period?  Last summer I had new BOA ratchets installed, and now I've just done new velco via a day visit to my local cobbler.  Impressive.  They still feel great.
