In flat feet, there is an absence of arch in the foot, meaning it is flat. The arch of the foot is what allows for shock absorption, while also contributing to momentum in walking and running.

If you are looking for the right athletic shoe for flat feet, you should keep in mind the following key features:

• Anti-shock protection at the appropriate points
• Durable stability
• Stable support of the arch
• Reinforced heel protection

The Brooks Adrenaline GTS 22 features an integrated GuideRails system, which is useful for proper alignment of the foot and knee.

The anti-shock protection provided by the BioMoGo DNA technology of this shoe can be adapted to each runner's stride. It has a spacious toe box, allowing for natural toe splay. This reduces the risk of blisters and other foot injuries.
