The "Invisibolt" Shoe Launch A major (unnamed) brand "leaked" a photo today of a shoe with 0mm stack height and 100% "air foam" that is literally invisible.

The "Super Trainer" Era Hits the Majors As we look toward the 2026 season, the "democratization of elite tech" is the name of the game.

The Rise of Supercritical Foams Forget the old EVA foam that dies after 300 miles; 2026 is the year of nitrogen-infused "Supercritical" compounds.

Is "Sustainable Running" an Oxymoron? 🌍👟

In the next episode of Sustainability in 26.2 series on What Runs a Run podcast, we sit down with Damian Hall, UK’s leading ultra-runners, famous for his exploits on the 268-mile Pennine Way, representing Great Britain at the World Championships, and taking on the mythical mud of the Barkley Marathons. But he’s also a journalist, a coach, a father, and increasingly, one of the most vocal advocates for ecological action within the running world. If you think sustainability is just about recycled medals, this episode will challenge you.

Here are 3 "Inconvenient Truths" Damian shared for runners and race organizers:
1️⃣ The 90% Rule: Participant travel (flights/driving) accounts for the vast majority of a race's footprint. We need to talk about "Racing Local" more than we talk about plastic cups.
2️⃣ The Power of "No": Damian recently walked away from major brand deals to stay true to the Game Changer Sponsorship Pledge. Integrity has a price, but silence costs more.
3️⃣ Longevity is Ecological: His new book Run Forever argues that staying fit into your 50s isn't just about PRs—it’s about becoming a long-term steward of the trails.

Whether you're an endurance athlete, industry professional or a race director, Damian’s "4 Pillars" framework is a masterclass in systemic change.
