I've only had them for two months and ONLY wear them in the ofc 9-5 on the carpet and the inside front is cracked already.  I am very disappointed because they fit great and matches to everything because of its neutral color but its a very cheap product.  I don't believe these can be true CK shoes because CK would not make such cheap products.  I had a pear for many years that I purchased from the store and those were much better quality.
