About Us

We are an ambitious group of people intent on changing everyone’s ability to play indoor sports free from ankle sprain injuries. Whether you love handball, basketball, volleyball or other indoor sports, we want to give you the tool to play your best.

We have conducted controlled testing in laboratories and on the court. The results are nothing less than amazing. They indicate that Spraino will dramatically reduce, if not eliminate, ankle sprains on the court. That gives our team even more energy to pursue fine tuning Spraino for everyone, in as many athletic pursuits possible.

We are always interested in meeting with teams and athletes ready to change up their performance – and stay on top of their game.
