Maybe. Some yoga experts claim you can rebuild your arches through a series of rigorous exercises over a long period of time. However, most people don't follow through with the exercises. So, that leaves us with a passive approach (custom foot orthotics) to correct unstable foot arches. As well, many people's arches drop as they age because they are forced to wear shoes to walk on hard surfaces either indoors or outdoors. In other words, most people are unable to exercise and strengthen their foot arches by walking barefoot on soft ground.
