Speedo Biofuse Training Fin

Speedo Biofuse® is engineered to perform with your body, offering superior comfort through fit. The human body combines the structural strength of the skeleton and the flexibility of muscles. The result is performance greater that its individual parts. This is the inspiration behind Speedo Biofuse® technology, where products are engineered to perform in harmony with the body. The interaction of structure and flexibility result in enhanced performance, comfort and fit. Our training aids are designed to help you get the most from your swim workout. Each training aid will work a particular part of your body, so you can focus on increasing strength, stamina or tone where it suits you.
