Tomorrow at OFFICE PDX (2204 NE Alberta), there’s a rare opportunity to take a peek into the archives of Nike alongside Design Director Chuck Eichten, who’ll be discussing what he does and how he does it. On display will be prototypes, test materials, collector’s items, and more. Sneaker freaks, make note. The event, from 6-8 pm, is free, but RSVP to info@officepdx.com.
