Holistic Silk use only the finest brocades to make their beautiful no-slip slippers. They have magnetic, massaging insoles that can aid leg and body circulation whilst giving you a soothing pain relieving foot massage. We think they are total relief after a long day on your feet, and perfect for in-flight relaxation. Also great for relaxing, travel, yoga and even in the office. Note: Before wearing magnets, consult a doctor if you are pregnant or have a pacemaker or a defibrillator. You can easily remove the magnetic insoles from our slippers.
