For most of us, sibling rivalry isn’t something we think much about once everyone in the family becomes an adult.

Most recently, this Athletic Interest piece went way more in-depth about both brands evolving from making shoes in laundry rooms to becoming the global sports’ powerhouses we recognize both brands as today.
