Every liquid filled shoe insole contains just enough liquid to gently form to your foot giving you arch support, shock absorption, and protection from sore, aching, feet, legs, and back. The gentle massaging action of the glycerin helps to stimulate blood flow in your feet and legs preventing fatigue and soreness most of us get from lack of circulation while standing or walking on hard surfaces. Foot Relief™ glycerin filled shoe insoles are approximately 1/8 inch in thickness and fit just about any shoe. Our special covering absorbs moisture and can be hand washed to refresh the insoles.
