Our group found the brace very effective at removing pressure from the rear of the foot but largely ineffective at removing pressure from the forefoot.
This project comes as a result of a Capstone project at Brigham Young University. The project was co-sponsored by the university and Pachyonychia Congenita Project, a non-profit that promotes research, advocacy and support for persons with Pachyonychia Congenita (PC), a rare genetic disorder that often involves extremely painful blisters and callouses forming on the soles of the feet. You can learn more abut PC here.
Step 1: Results from brace testing
The brace alone leaves little pressure on the foot. The pressure that is experienced is on the forefoot and is about the peak values of this pressure are reduced by about 33% compared to a normal shoe with an insole. The foam insert succeeds in lowering pressure peaks by about 77% by distributing the remaining pressure over the entire plantar surface.
