Running – and by default running footwear, performance, and athletic footwear – is surging worldwide, with marathon lotteries filling faster and race fields expanding across major global cities, and brands like HOKA and On omnipresent at major fashion weeks globally.
The accessibility of running (requiring little more than a pair of shoes and an open road) has helped fuel its growth.

In many ways, running footwear is driving the outdoor industry right now much like snowboarding once did for skiing and standup paddleboarding did for kayaking. It’s participation-based, accessible, and community-fueled; it feels new again. And brands that understand both performance and culture are defining this next chapter.
Founded in 1898, Saucony has long held key credibility within core run circles, but the Endorphin franchise marked a sharper inflection point for the brand in a modern performance system built around speed, propulsion, and efficiency. To that end, Saucony recently launched their Spring Marathon Collection featuring three new design iterations of the Endorphin Speed 5 sneaker with three bold city-forward designs inspired by the upcoming Tokyo, Boston, and London marathons. The Speed 5 remains anan up-tempo shoe, which quickly proves itself as more, equally capable of long, moderate training sessions, Zone 2 training, and sprints.
The collection continues a design tradition the brand has maintained for more than a decade.
As Chris Mahoney, VP of Design at Saucony, told Vanish, the company began developing marathon-themed seasonal collections to reflect the connection between running culture and the cities that host the sport’s most visible events. “Saucony’s seasonal Marathon collections started well over 10 years ago. As a brand, we initiated these projects because we were driven by the deep connection to running culture, especially the emotional energy and global reach of marathon running,” Mahoney said. “We love that these events celebrate both the sport and the cities that host some of the world’s biggest marathons. For Saucony, our goal has always been to create designs that resonate with both runners and enthusiasts, so it’s fun to draw on the unique character, culture, and race-day environment found at major marathons, which is showcased in the latest Boston, London, and Tokyo editions.”
Mahoney says that the design process for these releases relies on collaboration across Saucony’s global teams: “We have a strong creative and collaborative relationship with our teams around the globe, and the regional teams within these cities help contribute ideas and concepts so that we can create collections that resonate best.” When asked if he had a favorite shoe from the collection this season, he pointed to the Tokyo edition. “It’s tough to choose just one, but I’m very drawn to the Tokyo. I love the visual of the graphics on the upper and the overall color scheme. The subtle jade fade in the upper, adjacent to the metallic golden midsole, makes for a pretty striking visual.”

For Tokyo, Saucony wanted to capture the balance between tradition and forward momentum. The upper features a red plum blossom graphic inspired by 18th-century Japanese artwork — a symbol of resilience and renewal that still feels timeless. The golden haze tone along the midsole draws from the gilded gold in traditional art, while also reflecting the way the setting sun washes across Tokyo’s skyline. It’s a blend of heritage and modern energy, calm, refined, but always moving, which is “exactly what makes the city so compelling,” according to the brand.

The Boston design was inspired by the iconic color system of the Massachusetts Bay Transportation Authority (MBTA). Mahoney said it was fun to dig into the history behind each line — what the colors represent, the neighborhoods they connect, and how those identities came to be. After bringing all the MBTA colors together, subtle motion and blur across the midsole reflects the constant movement of the trains and buses that carry people in, out, and around the city every day. The upper is intentionally clean so the energy of the midsole stands out. And the crisp white upper naturally feels like spring in New England — a quiet nod to marathon season and the renewed energy that takes over the city each year.

London is layered with visual history, and red and gold are woven throughout the city. From the unmistakable double-decker buses and phone booths to ceremonial guard uniforms, red is instantly recognizable. Gold accents echo the detailing found on gates, statues, and historic architecture, giving the city its regal presence. Saucony pulled from that palette and incorporated a red rose graphic along the midsole as a tribute to England’s national emblem. At first glance, it reads almost like texture or linework. But the closer you look, the more you see the rose petals wrapping around the sculpted speed form. That subtle reveal felt right — it reflects London itself, where depth and detail unfold the longer you take it in.
The Spring Marathon Collection highlights how Saucony continues to connect product design with the broader culture of running, using global marathon cities as creative reference points while building on the performance foundation of the Endorphin Speed 5.
