A good sports bra can make every run better, as a poorly fitting one can be uncomfortable and frustrating.
To choose the best running bra, look for the highest possible support, as running is a high-impact sport. Sports bras are typically marked as supportive for low, medium, or high-impact activities.
A 2023 research by Frontiers in Sports and Active Living Journal has shown a 7 percent improvement in running economy in runners using high- over low-support sports bras.
Additionally, consider the architecture of the bra and how its features feel together, as this can affect the overall comfort and performance of the bra.
