The perfectionist biometric design of YogaToesÂ® Gems works wonders between, above and beneath toes to stretch toes apart from each other and outward, away from the ball of the foot. To simulate this effect, spread your fingers apart and out as far as you can. You can feel the muscles working and stretching. Fingers feel refreshed and invigorated. Tight, weak muscles become flexible and stronger. The posture of your feet will improve. Foot muscles are strengthened to maintain alignment. Stretching and working the muscles increase vital circulation where it is typically the poorest. You know how good you can feel after a workout or a massage. Now, your feet can enjoy the same benefits anytime! Just slip into your Gems!
