Insoles designed for men don’t address the effect of a woman’s increased quadriceps angle (Q angle) on her natural stride. When a woman runs, foot impact causes supination (outward rolling) followed by overpronation (the shifting of weight to the inside of the foot). Over time, these conflicting forces can lead to potentially serious repetitive strain injuries to the foot, ankle and knee. Spenco for Her® helps guide a woman’s natural stride into a centralized and balanced path.
