The Nike Flex TR 8 is designed for women who enjoy high-intensity workouts. Though it is made of lightweight materials, it offers the needed support and stability to push through with grueling exercises. This model retains the silhouette of its predecessor but much of the upper has been updated.

A full-length foam rubber makes up the outsole of the Nike Flex TR 8. This compound is made to be durable and provides traction on most surfaces. It features the Nike Flex technology, which is made of deep thin slits that aim to promote natural foot flexion.

The rubber pods are strategically placed in the high-wear areas of the outsole unit. They enhance the traction provided by the main outsole to prevent slippage. It also features the tri-star tread pattern which delivers multidirectional grip.

The Nike Flex TR 8 employs a dual-density foam midsole. This type of cushioning has firm and soft areas, each serving different purposes. The firm portion supports the foot, adding lateral stability. As for the soft part, it attenuates shock to keep the foot comfortable and protected. A very similar Flex unit is used in another women's workout shoe from Nike, called the Flex Supreme TR 6.

Inside is a molded insole. This thin component provides another layer of padding that reduces the shock to prevent any pain or discomfort to the lower extremities.

The upper of the Nike Flex TR 8 utilizes a closed-hole mesh fabric. This lightweight material is breathable to keep the foot chamber well-ventilated. It is engineered to be durable to withstand abrasion during intense workouts.

The footgear features no-sew medial and lateral panels that integrate with the lacing system. Together with the Flywire cables at the midfoot, they aim to bring a snug but non-restricting fit. The panels and the wires also enhance the lateral support provided by the upper.

The lightly padded tongue protects the instep from the laces. As for the slightly padded collar, it keeps the foot locked down and prevents chafing at the ankle area.
