The Nano 8 Flexweave belongs to Reebok's prominent line of CrossFit shoes and takes cues from the original Nano 8. What makes it different is the updated upper. The newer version has been re-engineered for enhanced breathability, support, and durability. It sports a Figure-8 construction that ventilates and reinforces targeted areas.

Durable rubber protection. The bottom of the Reebok CrossFit Nano 8 Flexweave is made from high-abrasion rubber. This compound is engineered specifically to deliver traction during dynamic routines involved in CrossFit and other high-intensity workouts.

Unhindered forefoot flexibility. At the forefoot, the “Metasplit” marking is clearly visible. It pertains to the deep grooves that mimic the phalanges of the foot, allowing the outsole to bend and move naturally with the foot.

Rope climbing add-on. The RopePro technology is seen at the lateral and medial sides of the midfoot. It has ridges that aim to bite the rope during rope climbs and descents for controlled motions.

All-around support. The shoe uses a dual-density midsole to fulfill the various demands of CrossFit. The heel area is created to be rigid to give support during lifts. On the other hand, the forefoot is more flexible and cushioned to cope with high-intensity fitness routines and plyometrics.

4-mm drop. Such minimal heel-to-toe differential grants secure footing to the athlete. It leads to a more stable platform during heavy lifts.

OrthoLite insert. Inside the trainer is the OrthoLite sockliner. This component not only enhances comfort but also helps in attenuating shock that travels to the foot and the rest of the lower extremities.

Two layers of comfort. This unit of the Nano 8 Flexweave has two layers: the outer Flexweave and the inner cleatie sleeve. The outer layer features an innovative Figure-8 weave that interlocks each fiber for a durable and flexible support. Meanwhile, the inner cleatie sleeve gives the foot a pleasant sock-like experience. It offers comfort and a snug fit at the ankle area.

Extra protection with Toe Tection. The Toe Tection technology is installed on the upper to boost durability. It reinforces the toe box to prevent ripping and protect the toes against bumps during specific workout movements.

Stabilizing heel counter. At the back, a thermoplastic polyurethane (TPU) heel clip can be found. This structure is rigid, cupping the rearfoot to keep it steady and prevent slippage.

If you are a fan of what the Nano 8 Flexweave has to offer, then you might as well check out its successor, the Reebok Nano 9. Based on many user reviews, the newer iteration does everything that the Nano 8 does, but better. It is also described to have better side-to-side support and a more running-friendly design.
