Nike’s latest release, the Nike Epic React Flyknit, features a soft foam that offers runners a smooth ride with excellent energy return. The proprietary React foam is engineered as one single piece to deliver maximum support and minimal weight in the shoe, while the Flyknit upper is constructed in one single piece to provide a snug fit on the foot. The outsole is a little thicker and wider than usual to counteract the soft compression of the foam and provide stability. The midsole and outsole are essentially the same material, but rubber has been added under the forefoot and heel for additional traction and durability. The heel clip keeps the foot secure and adds a pleasing aesthetic to the shoe.
Over the last few weeks of testing, the Epic React Flyknit experience has been excellent. The foam provides noticeable energy return, and that, coupled with the lightness of the shoe, makes powering up hills seem like less of a chore. The shoe is responsive on road and packed trail surfaces, and offers good traction in slick conditions.
