Good, chic shoe but with quirks

I still wear frequently Shoes K-Swiss, I ordered these shoes. It looks visually very good. However, the shoe is now broken after nearly fümf months. Namely, on the side is departed this white rubber namely at both shoes more or less simultaneously. I do not know if there is an application error on my part or a material error. However, my shoes have otherwise very much. Too bad about the money. I had K-Swiss shoes that I wore 2 years, without them went broke.
