DSX Flykit 2 vs. DSX Flyknit

Banking on the success of the original Metcon DSX Flyknit, this version features the same sturdy outsole with the tri-star tread pattern for exceptional grip on various surfaces. The rubber wraps up both sides of the shoe, protecting the knit upper during rope climbs.

- Like its predecessor, this model uses Nike’s proprietary Flyknit technology for the top half of the footwear. However, the upper has been redesigned and now sports a sock-like construction.

- What’s new in this version is the drop-in midsole. Though it is still 6 mm thick, the density and flexibility of this insert have changed. It is more flexible and less compressible compared to the old ones which appeared to be squishy.

- The back of the shoe lost its traditional collar and was replaced by a heel tab cushion. The heel clip is also less pronounced, but according to Nike, it’s more for aesthetic reasons than performance. However, this construction gets revised in the next iteration of the shoe, the Metcon Flyknit 3. The newer version sports a generously padded cleatie collar which extends up at both the front and the heel to keep the footwear securely around the ankle and eliminate undesirable heel slipping.


The Metcon DSX Flyknit 2 employs a full-length rubber outsole. The tri-star tread pattern delivers multi-directional traction. It is sticky in the forefoot area for added grip during sled pushes or other activities that require pushing off from the toes.

The rubber compound wraps the medial and lateral sides of the midfoot and serves as a rope guard. The textured surface helps the footwear grip the rope better when climbing while protecting the Flyknit upper from abrasion. The rubber also extends to the quarters and forms a heel clip that holds the back of the foot securely to keep it steady during explosive movements.


Designed with a low-to-the-ground sole unit, the Metcon DSX Flyknit 2 lacks a fixed midsole layer. It does, however, have a 6-mm drop-in insert that aims to bring shock absorption and protection to the underfoot. The removable midsole is also flexible to allow natural foot flexion. The component is made of dense rubber that does not readily compress to deliver a steady platform.


The Nike Metcon DSX Flyknit 2 utilizes the brand’s proprietary Flyknit technology. This fabric was crafted in response to the athletes’ need for a barely-there shoe that fits like a sock. It has been applied in many of Nike’s trainers.

In this model, the upper sports a single, continuous piece of Flyknit that resembles a sock. The form-fitting material is designed to be breathable, flexible and durable, not to mention supportive during workouts. The low-cut profile allows for unrestricted ankle mobility.

Because of its sock-like design, a lightly padded heel tab is used at the rear section to keep the Achilles comfortable and prevent blisters from forming. Pull loops are present on the attached tongue and the back of the heel tab. They make it easier for a user to put the shoe on given how it lacks a traditionally adjustable throat.

The footwear has a lace-up structure in the instep area. It does not function as a closure system, but a way for wearers to customize the fit of the upper. The laces integrate with the Flywire technology. The cables become taut when the laces are tightened, resulting in enhanced lateral support to the midfoot.

An internal heel counter cups the back of the foot. It prevents slippage and delivers a locked-down feel.
