TINKER HATFIELD SAW THE POMPIDOU CENTER AND PUT A WINDOW IN A SHOE

## 1987. Beaverton, Oregon. Tinker Hatfield was not a shoe designer. He was an architect who had spent six years designing corporate buildings for Nike's campus. He visited Paris on a work trip and walked into the Centre Pompidou, the museum where Richard Rogers and Renzo Piano had turned the building inside out, exposing every pipe, duct, and structural element on the exterior. Most people saw a museum. Hatfield saw a shoe. He returned to Beaverton and proposed cutting a hole in the midsole of a running shoe to expose the Air unit underneath. Nike's engineering team told him the air bag would pop. He did it anyway. The Air Max 1 debuted in 1987 at $98 retail. The visible Air window was 18mm of pressurized gas encased in transparent polyurethane, sitting in the heel where every stride compressed it visibly. Runners could see the technology working. The design principle was radical: instead of hiding innovation inside the shoe, show it. The Pompidou had done this with architecture in 1977. Hatfield applied the same logic to footwear a decade later. ## The OG Colorway That Started Everything The original Air Max 1 released in a white, grey, and red colorway that would later be known as "OG Red" or "University Red." That red panel sitting above the visible Air unit became one of the most recognizable color blocking patterns in sneaker history. The red was originally chosen because it matched the color of the Air bag when viewed through the window. Form followed function followed color. Nike produced limited quantities initially because the company wasn't certain the Air window would survive daily wear. The polyurethane window had a habit of yellowing over time and eventually crumbling, a flaw that would affect Air Max models for decades and eventually create a cottage industry of restoration specialists who replace deteriorated windows with fresh materials. The flaw became part of the shoe's charm. Collectors call crumbled soles "sole separation" and consider it evidence of authentic vintage pairs. ## London Adopted It Before Anyone The Air Max 1 found its deepest cultural home in London, where it became the uniform of football supporters, grime artists, and working-class fashion throughout the 1990s and 2000s. Londoners call them "110s" after the original UK retail price of £110. The shoe's connection to London street culture is so strong that Nike has released London-exclusive colorways annually for over a decade. When Skepta, Dizzee Rascal, and Wiley appeared in early grime videos wearing Air Max 1s, they weren't endorsement deals. They were wearing what they actually wore. Japanese collector culture embraced the Air Max 1 simultaneously. Atmos, the Tokyo sneaker retailer, created some of the most valuable Air Max 1 collaborations ever produced. The Atmos "Elephant" Air Max 1, featuring elephant print panels borrowed from the Air Jordan 3, sold out instantly in 2007, resold for over $2,000, and established Atmos as one of the most important sneaker boutiques in the world. The collaboration connected two Tinker Hatfield designs across twenty years of Nike history. ## Air Max Day and the $28 Billion Heritage In 2014, Nike created Air Max Day on March 26, the anniversary of the Air Max 1's 1987 release. The annual event has grown into Nike's biggest product marketing moment outside of new signature launches. Air Max Day generates hundreds of millions in revenue through retro releases, new colorways, and collaborative editions. The Air Max franchise now encompasses over 30 distinct models — Air Max 90, 95, 97, Plus, 270, 720 — all descended from the single window Hatfield cut into that first midsole. Nike's total Air Max revenue has exceeded $5 billion across the franchise's lifetime. The original Air Max 1 still accounts for significant annual sales because the silhouette has never been permanently retired. Unlike Jordan models that release in specific windows, the Air Max 1 maintains a perpetual presence on Nike's shelves in rotating colorways. The Air Max 1 proved that showing your technology creates more desire than hiding it. Every transparent phone case, every exposed-movement watch, every glass-back smartphone owes a conceptual debt to Hatfield's visit to the Pompidou. He didn't invent Air technology. Frank Rudy did that in 1977. Hatfield's contribution was the window. The decision to let consumers see the engineering changed how every product company thinks about design transparency. One architect looked at a building in Paris and created the most important midsole technology in sneaker history.
