injury issues
For the first time in many years, there are now more women runners than there are men. Despite this change, running footwear is still largely designed and manufactured for male runners. Not taken into consideration is the fact that women have significant injury issues compared to men.
ASICS technologies designed to address these issues


injury anterior knee

Anterior Knee Pain
Women have a significantly higher incidence of anterior knee pain (patellofemoral syndrome) than male runners.

injury gluteus mediusGluteus Medius Strain
Many women have major issues with fit and stability, probably because typically the female foot has a relatively narrower heel:forefoot relationship compared to men. This may lead to gluteus medius (butt) strains.

injury lateral knee

Lateral Knee Injury
There is a fundamental difference in the shape and structure of women’s feet compared to men’s feet. This could lead to more iliotibial band (lateral knee) injuries for female runners.

injury ligament damage

Ligament Damage
It is believed that higher concentrations of circulating hormones may be a significant factor in ligament injuries in women. The hormone estrogen, which is a soft tissue relaxant, may predispose female athletes to greater ligament damage. As estrogen levels change throughout the month, so does ligament elasticity. This becomes significant to female runners, specifically as the major ligaments in the arch can become flatter and less supportive.

injury lower back

Lower Back Pain
The result of the narrower heel:forefoot relationship can be heel slippage and reduced stability for women who may be wearing downsized men’s shoes. This can cause female runners to have many times more incidences of sacro-iliac (low back) pain as men.
