Nike.com's main site provides entry to a host of micro-sites for each sport or product family, but a consistent navigation model is provided across all microsites. A primary navigation widget is provided in the Nike Swoosh button, which reveals a list of a few of the most popular microsite destinations. A "More" link epxands the list to show all of the microsites.

1. Users click the Nike Swoosh logo to navigate across the Nike space to other microsites. A drop down reveals the most popular destinations.
2. A More link in the drop down reveals the entire list of microsites.
