The role of shoes, insoles and orthotics in making you move better

For two years I've been studying the effect of shoes, insoles and orthotics on a test for balance and motor control capacity. The test is called a Motor Control Screen, a derivative of the Lower Quarter Y-Balance Test, which is a derivative of the Star Excursion Balance Test. Here's the gist: only one person in two years scored better with shoes on, with orthotics in........so what does that mean?

Wearing shoes has not helped wearers to control their body movements when standing on one leg.
Wearing insoles, or custom made orthotics has also not helped wearers to control their body movements when standing on one leg. 

I'm going to leave it there. Happy to continue the conversation if you wish.
