Take control of your fit.

Whether you rely on your brace, prosthesis, or medical device at work, at play, or simply to help you get where you need to be, Boa helps you go further. The ability to make incremental single-handed adjustments throughout the day means you can control pressure and manage fit without ever removing your clothing, brace, prosthesis, or medical device.

Our medical partner Exos wanted improved fit and adjustability in this brace. We configured it with two easily accessible dials that independently operate the top and bottom lace crossings for superior and inferior compression, reshaping form, fit, and function. Ultimately, the patient receives superior decompression and support, a customizable fit, and overall improved comfort.
