Until not-so-long ago most running shoes for women were just smaller versions of men’s shoes. But, as understanding of the physiological structural differences between men and women has grown, so running shoes have thankfully become far more female-specific.
Over the past decade, scientific research has shown that women have different gait patterns and lower-limb biomechanics than men. This means that the way women run is significantly different, and it also helps explain why female runners have distinct injury patterns. For some years now ASICS has taken a gender-specific approach to designing running shoes, with the aim of improving women's performance, comfort and safety. This is great news for all new moms just getting into (or returning) to running and fitness training.
Women's feet are shaped differently. It's not just that women tend to have smaller feet than men, they also have a different heel to forefoot ratio. In other words, women have a narrower heel in relation to their forefoot. When wearing men's running shoes, this often causes the heel to slip inside the shoe, leading to instability and chafing.
For you: ASICS women's running shoes are shaped differently, using a narrower last. A gender-specific last dramatically improves fit for female runners and prevents problems like heel slippage.
Women tend to be lighter than men. Since cushioning in running shoes has always been designed with men's weight in mind, the cushioning material would often be too dense for women.
For you: We use a cushioning material called Solyte, but in a less dense form than its male counterpart. Located under the ball of the foot and extending across the width of the shoe, this material offers female runners greater impact absorption and more bounce.
Gender and gait
Studies have shown that a woman’s foot architecture changes as their oestrogen levels fluctuate during the month. Oestrogen is known to be a soft tissue relaxant, and one of the effects this has is to lower women's arch height. With each step, it means that the plantar fascia tightens and stretches in what is known as the windlass mechanism.
For you: For women the Space Trusstic was altered to accommodate for a lowered arch height, and give the plantar fascia sufficient space to develop tension and assist windlass mechanics. The Gender Specific Space Trusstic provides the female foot with the right levels of support and flexibility as it moves through the gait cycle.
