Hi all - I know there are a ton of Lanvin flat lovers here and I'm one of them. However, sadly after 4 years of regular use, the leather on both heels has worn away and on my right shoe is actually cracked right through to the footbed. I've seen a lot of pictures of used Lanvins that have this same problem and think it must be a design issue with the hidden platform. That said, has anyone successfully fixed this problem? Repaired them with a patch? Or is it time to bid them adieu? While I love Lanvin, I can't invest this much in flats that are going to do this again. Looking at Tieks or J Crew...any suggestions?
