U.S. JACLEAN Acupressure Shiatsu Massaging Magnetic Insoles (M(Men's 6.5-8, Women's 7.5-9)) Black

these are STRONG. New users may prefer to wear the sandals for a brief time each day to build up to wearing them full-time. The rounded acupressure nodules that stimulate the pressure points are made of a hard, durable plastic, and you will definitely feel the effect. Not suitable for those with very sensitive feet. 

These magnetic insoles are made of flexible plastic inserts that combine acupressure, reflexology, and magnets to provide gentle and effective stimulation to the feet. When walking in reflexology insoles, your feet massage themselves. Seven strategically-placed magnets and raised nodes stimulate reflexology points, alleviating mild to moderate foot discomfort and rejuvenating the entire body. With reflexology massage nodes and magnets, these insoles may help increase blood circulation to the feet and provide soothing pain relief. Massage therapist shoes are pricey, but with these easy insoles you can make your own. Raised areas give arch support while 250 air holes provide ventilation, keeping feet cool.
