branded shoes Watch
You wear them often: You like branded shoes and more that's why you bought them in the first place. Like everything else - you wear your branded shoes often and that is the reason why you see them disintegrate with time.
You don't store them well: Apart from wearing branded shoes, you need to store them very well. You have to keep them packed separately in a way that would help them stay clean and without being trampled on.
These are the reasons according to me that shorten the shelf life of branded shoes.
