When you step into Rykä, you step into more than a shoe--you step into a shoe specifically designed for women. This is because women’s feet are different than his.
A woman’s foot shape, muscle movement and build are all inherently different from a man’s. The "Q-angle"(or quadricep or quad angle), the anatomical relationship between the hip and knee. The quad angle, measures 5-7 degrees greater for women than men. As a result, women tend to shift more weight to the outside of their feet, which leads to instability at foot strike and higher risk of injury over time.
The Ryka design philosophy integrates the latest technologies into one of the most researched, women-specific fits in the industry. A complete footwear solution customized to fit the shape of a woman’s foot perfectly--with a narrower heel, roomier forefoot, increased instep volume and a more secure footbed.
The result is footwear engineered to address our unique biomechanics for unsurpassed fit, comfort, cushioning and control. So there you go. Now you know about the Q-ratio, also known as the quad angle. Please visit the website for more information.
