Get your tootsies summertime –ready with this natural scrub: In a bowl, combine 1/4 cup of finely ground walnuts with 1 cup yogurt. Then use a damp cloth to gently rub the mixture into hardened areas; rinse with warm water. The mildly abrasive quality of the walnuts will help slough away the dead cells while the yogurt’s milk fats replace lost moisture. The result? Soft soles that you proudly show off.
