Women’s road running shoes usually offer a narrower fit, lightweight midsole materials, a softer sole flex, and added pronation control to accommodate a woman’s biomechanics. Additionally, running shoes are divided into four categories that describe how the shoe supports the roll of your foot when it strikes the ground (how it pronates): neutral, motion control, stability, and minimalist. How you pronate dictates the general type of shoe you need: low arch/normal pronators should look for a stability shoe, flat arch/overpronators with excessive inward roll need a motion control shoe or stability shoe, and high arch/supinators (or underpronaters) should look for a neutral shoe.
Because women have wider hips than men, they have a wider Q-angle (the angle of incidence of the quad muscle relative to the kneecap). This means that women pronate slightly more than men, thus requiring a woman’s shoe to offer added pronation control.
Drop is a measurement of the difference in ground-to-heel and ground-to-toe height between your heel and your toe. High drop shoes will ramp your foot forward while low drop (or zero drop) shoes bring your heel and your toe level.
