The previous finding of a short-term FGA change \\>4 during Walkasins use (NCT02115633) justifies a pre-post study design to investigate the long-term effects of Walkasins use. Although the primary timeframe for the primary endpoint is 10 weeks, participants will return for follow-up visits at 26 weeks and 52 weeks of Walkasins use.\n\nThe investigators also intend to extend their observations of the short-term effects of Walkasins by replicating the randomized cross-over design of a previous short-term study. (The randomized cross-over replication will occur only during the baseline visit. The long-term study consists of a single arm.) This study may help to further refine the prescription criteria for Walkasins and determine whether or not the presence of a short-term response is indicative of long-term improvements.\n\nA subset of 10 participants at the Harvard Medical School site will be enrolled in a pilot study to investigate possible structural and functional changes in cortical areas of the brain related to somatosensory connectivity using magnetic resonance imaging (MRI).
