The Nike Free X Metcon 2, with its touted removable insole, promised a versatile training shoe capable of handling both high-intensity workouts and lighter runs. However, our initial assessment placed it among the lower-scoring shoes in our comprehensive CrossFit shoe review. While it undeniably delivered on comfort and running performance in certain aspects, significant shortcomings in key areas prevented it from achieving top marks. This in-depth analysis delves into the specifics of the Nike Free X Metcon 2, focusing on its removable insole and exploring the compromises inherent in its design philosophy.
Nike Free X Metcon 2 Review: A Balancing Act Gone Wrong?
The core concept behind the Free X Metcon 2 was ambitious: create a single shoe capable of fulfilling the diverse demands of CrossFit training. This involves navigating a delicate balancing act between the requirements of weightlifting (stability, support, durability) and running (flexibility, cushioning, responsiveness). Nike attempted to achieve this balance through a combination of features, including the aforementioned removable insole, a split midsole, and a distinct outsole design.
The removable insole, a key selling point, was intended to allow for customization. Users could remove it to create a lower profile for weightlifting, maximizing ground feel and stability. Conversely, keeping the insole in place provided extra cushioning and support for running and other less demanding movements. On paper, this sounded like a clever solution, offering adaptability rarely seen in a single training shoe. However, in practice, the execution fell short of expectations.
Comfort and Running Performance: The Strengths of the Free X Metcon 2
The Free X Metcon 2 undeniably shines in certain aspects. The cushioning provided by the midsole, especially with the insole in place, proved comfortable enough for moderate runs. The flexibility of the forefoot, thanks to the split midsole design, allowed for a natural range of motion, benefiting both running and dynamic movements within CrossFit workouts. Many users reported a comfortable fit, particularly praising the breathability of the upper. The overall feel, during lighter activities and runs, was often described as "springy" and "responsive," suggesting a decent level of energy return.
The removable insole itself, although not perfect, contributed to the comfort. Its presence provided a notable difference in cushioning, making longer runs and higher-impact movements more bearable. The ability to remove it for weightlifting, while not drastically altering the shoe's profile, did offer a slightly more grounded feel, improving proprioception for some users. This customizability, despite its limitations, was a noteworthy feature.
Weightlifting Performance: Where the Free X Metcon 2 Falters
While the Free X Metcon 2 performed adequately in running and lighter movements, its shortcomings became glaringly apparent during weightlifting exercises. This is where the compromises made in pursuit of versatility became most evident.
The midsole, while comfortable for running, lacked the stiffness and stability required for heavier lifts. Many users reported a noticeable amount of flex in the midsole during squats, deadlifts, and other compound movements, leading to a feeling of instability and reduced confidence. This lack of rigidity compromised the shoe's ability to provide a stable platform for weightlifting, potentially increasing the risk of injury.
Even with the insole removed, the remaining platform still lacked the firmness and unyielding support found in dedicated weightlifting shoes. The outsole, designed with flexibility in mind for running, proved too flexible for the demands of heavy lifting. The lack of a pronounced heel counter further contributed to the instability, particularly during movements requiring significant heel elevation.
