Competing Interests

Please note that there is no formal affiliation with the International Children’s Orthotic Laboratory which is owned by Dr Heather Netscher, who is a co-author on the paper. Dr Netscher’s company is primarily focused on podiatric problems in children and not with people with Parkinson’s disease. Her company contributed to the manufacture of the textured insoles without any expectation of immediate or future financial benefit. There is no patent associated with the insole and the authors have elected to publish details as an open-source paper so that it is freely available. This does not alter our adherence to all the PLOS ONE policies on sharing data and materials.
