Textured insoles:What's your take?

One of our readers writes:

I saw the video on cross over running, it was very good. It appeared the glute Med was inhibited and that the penguin walk assisted in activating it. My question is what your philosophy is regarding slightly textured insoles and if this may affect hip and abdominal function and cross posture syndrome?

 Our Response:

Thanks for the kudos. Textured insoles are probably a good thing, as they can help provide more proprioception from the feet (which have a tremendous amount of cortical representation).  They could conceivably affect hip and abdominal function. The research out there seems to be focused on people with MS, but here is another supporting study: http:// www.ncbi.nlm.nih.gov/pubmed/18246902
