Why Shoe Stack Height Matters For Running Shoes — And How Tarkine Strikes the Perfect Balance

Why Shoe Stack Height Matters For Running Shoes — And How Tarkine Strikes the Perfect Balance - TARKINE ATHLETICS

When it comes to running shoes, there’s one often overlooked detail that can make a massive difference to your comfort, performance, and injury risk — stack height.

What Is Stack Height?

In simple terms, stack height is the amount of material between your foot and the ground. It’s measured in millimetres from the outsole (bottom of the shoe) to the insole (where your foot sits). A higher stack means more cushioning. A lower stack means a closer-to-the-ground feel.

Why It Matters

The stack height of your shoes influences:

  • Cushioning & shock absorption

  • Ground feel & responsiveness

  • Weight of the shoe

  • Stability, especially on uneven terrain

  • Fatigue levels on long runs

For example, ultracushioned shoes with super high stacks might feel soft and forgiving, but can also be unstable on trails or turns. On the flip side, low-stack minimalist shoes can be responsive but harsh over long distances or harder surfaces.

The Tarkine Approach: Balanced Geometry

Tarkine’s design philosophy focuses on balance, not extremes. We’re not chasing max-stack trends or barefoot minimalism. Our goal is to create shoes that perform across all distances and conditions, without compromising on comfort or control.

  • Trail Devil 2: Built for rugged terrain with a 33mm forefoot / 39mm heel stack height. This gives you cushioning for ultras without losing ground feel or grip.

  • Autopilot: A road cruiser with a plush 34mm forefoot / 40mm heel geometry — designed for smooth, efficient miles while still feeling stable underfoot.

  • Goshawk V2: Our everyday road warrior. Light, responsive, and built with a 25mm forefoot / 31mm heel stack — ideal for everything from tempo runs to marathons.

Each model has a 6mm heel-to-toe drop — a sweet spot that encourages natural movement while still supporting your calves and Achilles on longer runs.

Why It Works

The feedback from Tarkine runners says it all:

  • “Soft where it needs to be, stable where it matters.”

  • “I don’t feel beat up after long runs.”

  • “Perfect balance — not too mushy, not too stiff.”

Whether you're smashing trail ultras or logging weekly road kms, stack height isn't just a number — it's a key part of your ride. And we’ve obsessed over every millimetre to make sure it works for you.
