About Us

Shinfin Pty Ltd was established in 2002, to develop shinfin swim fins and bring them to the world. Thank you very much for your interest.

I am passionate about designing natural swim fins to match the natural biomechanics of good swimmers. I aim to help all levels of swimmer to improve their technique and fitness, for swimming and many other water sports. Most important, is a proper streamlined body position with a natural streamlined kick. Natural good swimmer biomechanics. shinfin swim fins are indeed a natural swim fins design. It feels like you are swimming barefoot but with more power and speed. The end result, is fins that enhance the enjoyment and benefits of swimming and many other water sports.

Developing revolutionary new fins that attach to the legs is a long and exciting road. Of course it requires science, design engineering and a huge amount of prototyping and testing. But most essential is a good dose of humility. Because, in the end, it all comes down to some fundamental questions. Do the fins feel natural? Do people like using them?

So my heartfelt thanks go out to the thousands of people who have tried shinfin swim fins (prototypes and production) and who have been kind enough to give me their honest feedback.

Australian Government Support

The AusIndustry R&D Start Program (Commonwealth Government of Australia) awarded us two grants for shinfin swim fins research and development. So we are very grateful for this support.

The Australian Technology Showcase (New South Wales Government, Australia) selected us for membership. This helped to develop export markets for shinfin swim fins. So we appreciate their assistance too.

University of Edinburgh Research

The University of Edinburgh (Scotland) helped our research with 3D video analysis of swimmers wearing shinfin swim fins. They did this research at their specially constructed swimming pool at their Centre for Aquatic Research and Education (CARE), at the Department of Physical Education Sports and Leisure Studies (PESLS). So many thanks for this research.
