If you’ve spent any time in a CrossFit gym, you’ve probably noticed a common trend on people’s feet: Reebok Nanos. As one of the earliest shoes designed specifically for CrossFit, the Nano has become a staple in the fitness community. But with the market now flooded with cross-training options from Nike, Nobull, Under Armour, and others, how does the latest Reebok Nano hold up? Are these still the best CrossFit shoes out there? Here’s a full, honest review from a performance and functionality standpoint.
A Quick History of the Reebok Nano
Reebok launched the first Nano in 2011 after becoming the official footwear sponsor of CrossFit. Each new iteration has aimed to address athlete feedback—improving durability, flexibility, and performance in line with the varied demands of high-intensity workouts. The latest models, such as the Nano X3 and Nano X4, continue this tradition, offering innovative features tailored to modern fitness needs.
Design & Build Quality
Looks and Aesthetics
The Reebok Nano has evolved into a sleek, functional shoe that doesn’t scream “gym rat” but still delivers serious performance. Recent versions have more lifestyle-friendly styling, which means you can wear them outside the gym without looking out of place.
Construction and Durability
Reebok’s Flexweave® knit upper is one of the Nano’s standout features. It provides excellent breathability and durability, resisting abrasions during rope climbs, box jumps, and dragging your feet through burpees. The reinforced toe box adds protection and structure, while the solid heel clip enhances stability under heavy loads.
Performance Breakdown
1. Stability for Lifting
The Nano truly shines when it comes to weightlifting. The wide, flat sole and minimal drop (typically around 4mm) offer a solid base for squats, cleans, and deadlifts. Whether you’re doing heavy Olympic lifts or tempo back squats, the Nano provides dependable grounding without sacrificing comfort.
2. Versatility in WODs
CrossFit workouts combine everything from sprints and kettlebell swings to rope climbs and handstand pushups. The Nano performs well across the board. It’s flexible enough for jumping and short-distance runs but supportive enough for dynamic lateral movements and plyometrics.
3. Comfort & Fit
The Nano is known for its roomy toe box, which allows for natural foot splay during lifts. The fit through the midfoot and heel is snug without being restrictive. Whether you’re on your feet for 30 minutes or two hours, the cushioning feels balanced—not too soft, not too firm.
