ryka's ANGLE ON PERFORMANCE

For over 20 years, ryka has been innovating athletic footwear exclusively for women. In fact, everything we create is designed by women. From the shape of her foot to the angle of her stride, we understand that women require more than just a downsized version of a men·s athletic shoe.
the science
Ryka knows that a woman's foot shape, muscle movement, and skeletal structure are all inherently different from a man's. The "Q-angleTM (quadricep angle) - the anatomical relationship between the hip and knee - 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 over-pronation, instability at foot strike, and higher risk of injury.
our solution
Ryka's design philosophy integrates all of our technologies into one of the most researched, women-specific lasts in the industry. A complete footwear solution that fits the shape of a woman's foot perfectly - with a narrower heel, roomier forefoot, increased instep volume, and more secure footbed. The result is a high-performance, athletic shoe engineered to address the unique biomechanics of active women for unsurpassed fit, comfort, cushioning and control.

ryka TECHNOLOGY

for cushioning
NITRACELTM CUSHIONING CARTRIDGE: Engineered from Nitrogennfused foam, this innovative heel cushioning cartridge absorbs impact and provides energy return for a smooth, resilient ride.

N-GAGETM: High-grade EVA foam and premium rubber combine to create a super lightweight cushioning and rebound system that continues to exceed industry standards.

N2-DMTM (NITRACELTM DAMPENING MATERIAL): Our most advanced cushioning technology uses a flexible NitracelTM foam compound to deliver high-level shock absorption and energy return, typically located in the heel and forefoot areas, where women need it most.

for control
Q-Angle P.C.TM (Quadricep-Angle Pronation Control): A dense durometer of material [usually grey in color) located at the medial section of the midsole platform on various ryka shoes. Based on Q-Angle research, women tend to shift their weight outward upon impact. Q-Angle P.CTM assists in the controlling process of accurate foot strike alignment from heel-to-toe transition.

S.G.S.TM (Skeletal Guidance Shank): Uniquely engineered to keep the shoe lightweight yet provide mid-foot support during heel-to-toe transition. The S.G.STM works with the other technologies built around it by acting as a center frame stabilizer.

I.H.G.TM (Infused Heel Guidance): Designed to provide extra lateral stability support, this infused TPU clip works with the midsole to secure the heel and guide foot strike alignment.

for comfort
C2TM Cartridge: A highly innovative cushioning system engineered with an encapsulated Visco-Elastomer pack, with active spheres that provide a spring like quality for superior performance, cushioning and comfort.

OrtholiteTM Footbed: A molded, highly engineered comfort footbed that provides maximum ventilation, wicks moisture, is tear proof, has antimicrobial built in the foam compound and is hand washable.

Dorsiflexion: Is the upward movement of the foot at the ankle joint.
