To determine the effectiveness of The Healing Sole Flip Flops, a clinical trial was conducted by Dr. Meredith Warner, orthopedic surgeon and inventor of The Healing Sole.

The clinical trial looked at the feet of 22 patients with a history of chronic foot pain associated with plantar fasciitis. Patients answered pre and post study questionnaires on foot pain and function.

Patients saw an overall improvement in pain and function during the course of the study.

In conclusion, the study resulted in an 80% success rate in the improvement of pain and/or function. No adverse effects were seen during the clinical trial.
