I had these for a couple years but that is still no excuse I barely wore them and yes I did notice that they changed the material that’s on the soles on the most recent ones I have reached out to the CHANEL hotline and they said that I would have to deal with this once stores open back up so I am just going to wait until then to see what they will be able to do for me I loved these I’m very disappointed I don’t even want another pair I really just want a credit
