Stack Height

How to choose he best stack height shoe for your run

One factor to consider when choosing a running shoe is how the shoe feels under your foot. This underfoot experience is largely determined by the amount of material between you and the ground, which is referred to as stack height.

Stack Height Image Example

At Running Warehouse, we group shoes into six stack height classifications. Lowest to highest they are: Barefoot, Minimal, Low, Medium, High and Maximal. Generally speaking, lower stack heights deliver more feel for the ground and higher stack height shoes deliver more feel for the cushioning materials of the shoe.

*Stack height classifications are determined by the forefoot measurement of a shoe.

While flexibility and softness of the shoe, weight of the runner, and speed and distance of the run influence the underfoot feel, stack height is the main factor in perceived cushioning. Thus, shoes with lower stack heights tend to have a firmer, responsive underfoot feel, while higher stack height shoes tend to have a softer, more compliant feel.

Buying Guidelines

In the most general and simple context, follow this idea: If you are feeling beat up, move up a stack height. Need more speed? Try moving down a stack height.

High or Maximal: Best for long runs. The longer the run, the more this height may provide a benefit. Also, they are a great option for easy runs or recovery runs.

Medium: Most runners, regardless of experience log most of their miles with this stack height. If you seek a little more padding for daily use then go to a high stack height shoe.

Low: Best for faster pace workouts. Advanced runners often use this height for regular training as well. Beginning runners may look at this height as a starting point for their first race-specific shoe.

Minimal: Most racing-specific shoes are found here. Can also be used for faster training if you are an efficient runner, or regular use if you seek a minimalist running experience.

Barefoot: Best for limited use such as speed work or strides. May be used for occasional short runs on soft surfaces like grass.
