Good to know
- Like other Metcons, the Metcon Flyknit 3 employs a low-profile midsole for stability, but this model has an extra layer of sturdy rubber at the heel for added steadiness.
- Another feature it shares with recent Metcon releases is the Tri-Star tread pattern on the rubber outsole for traction in any direction. It also serves as a rope guard at the midfoot.
- As the name implies, Flyknit is used in this iteration. This fabric provides a dynamic fit that adapts to the shape and movement of the foot.
The Nike Metcon Flyknit 3 employs a durable rubber outsole. It features the Tri-Star tread pattern that provides multi-directional traction while also rendering flexibility at the forefoot. The outsole is constructed to be flat at the heel and under the arch to keep the foot steady. The rubber wraps up the medial and lateral sides of the trainer to offer grip during rope climbs.
A low-profile midsole adorns the Nike Metcon Flyknit 3. It provides the shoe with shock-absorbing properties, but its low-to-the-ground construction keeps the foot steady during weight training. There’s also a firm rubber compound wedged between the midsole and the outsole at the heel that helps in keeping the rearfoot stable.
Inside the trainer is a drop-in midsole. This component amplifies the shock attenuation of the midsole to keep the foot comfortable.
The upper of the Nike Metcon Flyknit 3 is made up of two fabrics. The high-tenacity Flyknit material forms the vamp and the quarters while the back portion uses a soft cloth covering. The Flyknit is pliable to accommodate different foot shapes and the natural foot expansion that happens during training. It is also breathable to keep the foot fresh.
Synthetic overlays are present on high-wear areas such as the toe box, the lateral quarter, and the heel to prevent early degradation of the underlying material. The rearfoot utilizes a suede overlay that acts as an external foothold.
The footgear sports a cleatie style which makes it easy to put on and remove. There’s a lacing system at the midfoot that keeps the foot securely in place. The Flywire cables integrate with the laces. Cinching the laces make the Flywire taut, thereby reinforcing the lateral support of the upper. A thermoplastic polyurethane (TPU) wing makes up the first two eyelets which lock the ankle down.
The collar and the tongue are plush to prevent discomfort and keep the fit snug. A tab is attached at the back of the collar which makes it easier for wearers to pull the footwear on.
