Singletrack Why Trail Running Still Hasn’t Had a "Vaporfly Moment" (Geoff Burns Explains)
In this episode of the Singletrack Podcast, I chat with sport scientist and physiologist Geoff Burns to unpack one of the biggest open questions in trail running right now: why shoe technology hasn’t produced a single, decisive “Vaporfly moment” on the trails - and whether it ever will.
Geoff explains why trail running is fundamentally different from road running when it comes to performance gains. While road shoes can be optimized for straight-line efficiency on uniform surfaces, trail shoes operate in a far more complex system - one shaped by uneven terrain, gradients, stability demands, traction, weight, and constantly changing conditions
Geoff explains:
* Why super-shoe logic breaks down on trails
* The real role of foams, plates, and energy return off-road
* Why shoe tech gains often disappear on uphill, downhill, or technical terrain
* Whether trail shoes are nearing saturation—or still wide open for innovation
* How weight, traction, durability, and stability compete with pure efficiency
* Why different trail races may require entirely different “optimal” shoes
* What shoe tech might be changing in the sport
