Is it fine to put multiple breadcrumbs on the same page?

e.g.
Home > Shoes > Basketball Shoes > Nike > Air Force I
Home > Nike > Shoes > Basketball Shoes > Air Force I
Home > Shoes > Men's > Air Force I

The URL of a product page (Air Force I) doesn't change. It's fixed. Can this confuse search engines?

I also wonder which is picked up as Rich snippets in SERPs if I implement markup for breadcrumbs to all?
