Wondering how to sort through all advice on running bras out there? We’re here to help. Our bra designers and developers teamed up with biomechanical researchers to find out the truth behind five common sports bra myths.
Myth 1: There’s only one correct sports bra support level for running
Our biomechanical experts at University of Portsmouth found that most women preferred a similar range of support for running, but that there’s no best sports bra support level. That’s why we no longer categorise by level of impact/support. Our run bras are all built within the range that women told us felt most comfortable.
Myth 2: You have to wear your measured bra size
How to choose your sports bra size isn’t just following your normal bra size. Although measurements provide a great starting point and are often accurate, that’s not always the case person-by-person. You should first measure, then try and make sure that the fit feels right for your body. Check out our fit guide for extra tips. It is more important that a sports bra fits well than that you depend your size in sports bras on your normal bra size.
Myth 3: Wearing an unsupportive bra isn’t that bad
Working with our partners in Portsmouth, we learned that when women wear a bra without enough support, they can lose up to 4 cm of stride length due to poorly controlled breast movement — that’s an entire extra mile over the length of a marathon! No thanks!
Myth 4: Wearing two sports bras offers double the support
We’ve all seen women do this, but we wish they knew they didn’t need to! Wearing a bra that’s designed for running and fits correctly is the best way to get the right support. No need to be wearing two sports bras!
Myth 5: Bras with built-in cups are more supportive than bras without them
It’s true that built-in cups offer one kind of support — their structure can help prevent bouncing — but depending on your body type and what you find comfortable, you may prefer bras that use compressive fabric instead of built in cups. There’s no wrong answer here! Find what you like and go with that.
