Ankle Sprains are painful and extremely annoying. That is why Exo-L introduces an innovative protection method, a natural extension of your own body. 

The TU Delft start-up is developing an improved ankle brace to prevent sprains, without restrictions. Marcel Fleuren's cum laude final project was chosen by TU Delft as one of the best innovations of 2011 and patented on 10 June 2011.

Goals of the project

The goal of the improved ankle brace is to prevent millions of ankle sprains worldwide.
