The Nike Metcon 9 stands out as a top-tier cross-training shoe designed primarily for weightlifting and heavy compound movements. Reviewers praised its exceptional stability, durability, and performance on rope climbs, making it ideal for serious Crossfit athletes and lifters. However, its weight and limited suitability for cardio exercises were noted as drawbacks. The shoe offers a comfortable fit and good grip on gym floors, though it lacks cushioning for high-impact activities.
Full review
Minimal cushioning for stability
The Nike Metcon 9 maintains a very low stack height that prioritizes stability over comfort, with a heel stack of 21.5 mm and forefoot stack of 16.0 mm. This minimal cushioning design is intentional for weightlifting and Crossfit activities, providing the grounded feel that athletes need for controlled movements. However, this design does not translate well to high-impact exercises like rope jumping, where the lack of cushioning makes the experience uncomfortable. The dual-density midsole provides a firm platform that supports heavy lifting, but the overall construction feels less forgiving underfoot during dynamic movements.
Wider toe box with mixed results
The Metcon 9 introduces a notably wider toe box compared to previous models, addressing long-standing complaints about toe confinement. This change allows for better toe splay and grip during lifts, which is particularly beneficial for athletes with wider feet or those who perform toe-based exercises regularly. However, this increased width comes at a cost to fit security, as some users report their feet moving left and right inside the shoe during intense workouts. The wider toe box also affects the overall upper structure, which becomes less secure and can lead to foot slippage during dynamic movements. While the toe box accommodates wider feet, it compromises the locked-in feel that many lifters prefer for stability.
TPU heel causes discomfort
A persistent issue in the Metcon 9 is the TPU heel counter, which creates a clunky and uncomfortable experience during walking and running. The hard plastic heel tab, known as the hyperlift, is designed to provide stability for heavy lifts but proves to be unforgiving during non-lifting activities. The TPU heel rubs against the ankle and causes irritation, particularly for users who wear the shoe for extended periods or walk frequently. This feature, while functional for weightlifting, significantly impacts the shoe's versatility and overall comfort outside of the gym. The larger hyperlift in the Metcon 9 compared to the Metcon 8 makes this problem more pronounced.
Durability and construction quality
The Metcon 9 demonstrates solid construction quality with a durable upper and outsole that withstands regular Crossfit use. The mesh upper with haptic overlays and rubber rope guards provide good protection against wear, although they contribute to poor breathability. The dual-density midsole construction is robust and maintains its shape well under heavy loads, supporting the shoe's reputation for longevity in intense training environments. The overall build quality reflects Nike's commitment to creating a durable training shoe.
Performance in lifting vs cardio
The Metcon 9 excels in weightlifting scenarios, offering excellent stability and support for heavy lifts such as deadlifts and squats. The dual-density midsole and TPU heel provide a firm platform that helps maintain balance during complex movements. However, the shoe's performance in cardio activities is subpar, with users noting that it lacks the flexibility and responsiveness needed for running or HIIT workouts. Athletes who primarily focus on lifting and Crossfit will find the Metcon 9 effective, but those seeking a balanced training shoe may be disappointed with its limitations in other activities.
Sizing and fit considerations
The sizing of the Metcon 9 is generally true to size, but the wider toe box and higher heel counter create unique fit challenges. Users with narrower feet may find the shoe too roomy, while those with wider feet benefit from the increased toe room. The higher heel counter in the Metcon 9 can cause ankle irritation, particularly for users who are sensitive to heel rubbing. The removable insole allows for customization, but the overall fit remains inconsistent across different foot types. The shoe's fit is described as medium to wide, with some users noting that it feels slightly smaller than expected. Sizing recommendations suggest going with normal shoe sizes, but the fit can vary significantly based on individual foot characteristics.
Price and value proposition
At $150, the Metcon 9 carries a premium price point that may not justify the incremental improvements over previous models. The slight redesign and minor construction changes do not provide enough value to warrant the price increase, especially when compared to the more affordable Metcon 8, which offers similar performance at a significantly lower cost. The shoe's performance in lifting activities is strong, but its limitations in cardio and general comfort make it less appealing for athletes seeking a versatile training shoe. The price point is particularly questionable given that the improvements are minimal and the shoe's design has not addressed key user complaints. For those who prioritize weightlifting performance, the Metcon 9 may be acceptable, but the value proposition is weak for general training use.
Strengths
- +Exceptionally stable for weightlifting
- +One of the most durable cross-trainers
- +The best shoe for rope climbs
- +Reliable foot containment
- +Very comfortable in-shoe feel
Watch-outs
- −Heavier than average (and previous Metcons)
- −Not great for cardio workouts and rope jumps
How it compares
The Nike Metcon 9 stands out as the most stable and durable cross-trainer, excelling in weightlifting and rope climbs, but it's heavier than the Reebok Nano X3 and NOBULL Trainer+, which offer better cardio performance and lighter builds. Unlike the Under Armour TriBase Reign 5, it lacks cushioning for high-impact activities, making it less versatile for runners or sprinters.
