Transformative
"Radical reduction in tiredness at the end of the day from standing or walking, for feet with high arches ie only back of heel and front of sole underneath toes, actually make a footprint on a flat surface. Having feet now well supported under their arches, puts knees and hips in the right place for standing and walking without feeling horribly tired at the end of the day. Wish I had know about these decades earlier, but at least I do now!"
