RYKA Women's Vida RZX Cross-Training Shoe, Enamel Blue/Deep Lilac/Aqua Sky/Mint Ice, 10 M US
The pinnacle of Ryka performance, this training shoe features the new RZX technology platform. RZX provides both flexibility and cushioning in a training shoe. Featuring Ultra Flex in the forefoot, the alternating flex grooves on the top and bottom of the midsole, and in the rubber outsole, RZX reduces forefoot pressure during workouts. RZX features RE-ZORB in the heel, designed to absorb impact and provide cushion all the way to the flex zone, providing maximum comfort so you can focus on the workout. A supportive and breathable upper provides support and allows for flexibility in all the right areas.
