I never found Lanvin shoes comfortable so after a pair, never again. I gave the Lanvins to my mother thinking her with smaller feet might find them comfy and she didn't like them either. Unfortunately I can't contribute much on the wear and tear of the satin sneaky vivs, I have not worn them enough. However because they are satin I am extra careful and don't wear them if it looks like it is going to rain; which I find quite bothersome to have to worry about shoes. I think if you love them maybe just a pair in your collection is more than enough.
Yes so agreed, Lanvin shoes were not the most comfortable shoes I owned and reinforced my decision to continue with RV! Thank you for your feedback on satin. I may just wait to see what they bring out next season. xx
