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

This particular sibling rivalry was tackled in one of our favorite Great Big Story Videos years ago. 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.
