Thank you for sharing your feedback Sabrina! We're delighted to hear you find the Essential Bra comfortable. Please note that the shoulder caps are designed to provide optimal support during mostly stationary activities, such as desk work, meditation, reading, or even relaxing. While they may shift during more dynamic activities, you should still experience the benefits of our PostureCue technology. We appreciate your support and hope you continue to enjoy IntelliSkin products. If you have any further questions feel free to reach out to us at support@intelliskin.net.
