First and foresmost, the Brooks Beast/Ariel 20 features durable DNA Loft cushioning that is incredibly soft and responsive. We find this versatility is demonstrated in almost every feature of the shoes.
If comfort and cushion is your main priority, then these running shoes will prove to be a winner. Regardless of the speed, trail type, or any other factors, the Beast/Ariel 20 is up for the task and keeps feet cozy.
What’s more, with the addition of guide rails, the feet will not move with unnecessary lateral slipping. This prevents unnecessary strain on the arches and tendons of the feet.
Not only that, these guide rails send the foot into a comfortable an more natural/neutral stride upon toe-off. As a result, runners with collapsed arches will also find relief from any knee or ankle pain.
