MARUGO Wellness Earthing Tabi Mustard Color 23.5cm Retail Price: ¥13,000 Purchased the year before last and used for two seasons. Washed with soap and water, but there are stains that won't come off. There is no peeling of the soles, and they can still be used as earthing shoes. A special pair of socks is included as a bonus so you can use them in winter. Please let me know if you don't need them.
