One of 4 pairs of Blue Ribbon Sports shoes in the collection.

Waffle sole material added upon arrival in Eugene in Bowerman and Vixie's shop.

Jeff Johnson is of two minds about these shoes - that they are BRS, but that there's a possibility that they are. If so, Bowerman may have altered these upon arrival.

"These shoes are a mix," he said.

He further said that the tops are not earlier than 1971 and not later than 1974.
