The Free x Metcon is the first shoe in which Nike fuses two of its prominent footwear lines: the Free and the Metcon. While the Nike Metcons have proved themselves to be hard-wearing and stable CrossFit shoes, the Nike Free trainers are designed with flexibility and natural running motion in mind. The marriage of these technologies is meant to address one of the most common demands coming from CrossFit aficionados - a shoe you could lift, run, and jump in.
The bottom of the Nike Free x Metcon is made from two types of rubber. One is the carbon rubber which is one of the most durable types, while the other is blown rubber that lends a cushiony and lightweight feel to the outsole.
It uses the Nike Free technology which is comprised of laser-siped flex grooves for seamless lateral movements and flexibility. The tread features tri-star patterns, some of which are compressible and some are rigid to render a combination of support and pliability.
The inner midfoot is wrapped in a rigid block of TPU and rubber. It guards the footwear against the abrasions and friction caused by rope climbs.
Smooth low-profile heel clips are located in the lateral and medial sides of the outsole. They reduce the drag from the wall during handstand push-ups.
The Nike Free x Metcon employs a dual-density midsole. It features a soft compound which is housed in the firmer one with the use of a cold fusion technology. It is meant to balance plush comfort and stability.
The shoe sports a cleatie upper that is made of mesh covered in TPU. It is engineered to provide flexibility, support, breathability, and durability. The mouth and the heel area are made of neoprene, which is a breathable, smooth, and cushioned material.
TPU sidewalls wrap around the midfoot for lateral support. They keep the foot centered in the midsole during side-to-side movements. They also have holes that serve as eyelets, enabling the tester to adjust the tightness of the footgear. In the 2nd iteration of the Free x Metcon, this cage has been moved to the midfoot for enhanced support.
A traditional lacing system is used for a secure foot lockdown. It works with the Flywire technology, a set of filaments that operate like cables on a suspension bridge. It delivers support and snug fit.
