They worked as advertised and I think they're gonna last a really long time and they're probably the best CrossFit shoes out there right now, but just barely.
The addition of a more rigid heel cage gives you that extra support and stability during squatting and lifting.
If you’re looking for the definitive fitness shoe, this is it.
The Reebok CrossFit Nano is designed specifically for CrossFit and this is what they do best. For CrossFit enthusiasts, they are the best option.
Honestly, I haven't found any flaws.
So, the main premise behind the Nano 4.0’s is you don’t know what CrossFit workout will be presented (especially at the CrossFit Games), but you do know that the 4.0’s are the ideal shoe for any movement.
The Reebok CrossFit Nano 4.0, as the name implies, is a shoe created specifically for CrossFit. It is equipped with technologies that provide support, steadiness, and agility, assisting the wearers’ throwdown at the box.
The trainer shares a striking resemblance to its predecessor, the CrossFit Nano 3.0 thanks to the Duracage protective cover. Though the design of the structure is more refined in the CrossFit Nano 4.0. The most obvious difference is the absence of the Reebok Vector logo on the lateral side of the Duracage in this new iteration. Instead, the Delta logo is more prominent, along with the CF74, a nod to the year 1974, the year CrossFit was born.
The underside of the Reebok CrossFit Nano 4.0 is protected by a rubber compound manufactured to be durable to withstand training on rough surfaces. It features a tread pattern that promotes multi-directional traction. It also wraps up the medial and lateral sides of the midfoot, forming the RopePro structure that bites the rope, assisting wearers to ascend and descend cables.
Examining the bottom of the footwear, there are noticeable ridges called the Metasplit. They mimic the phalanges of the foot, allowing it to bend and move naturally.
The midsole of this Reebok trainer is made up of two compounds. The forefoot uses the F48 cushioning unit that not only attenuates shock but also promotes flexibility. The midfoot and the heel are lined with the S55 material which also absorbs shock, has a high energy return, and is solid to keep the rearfoot steady during plyometrics, lifts, and squats.
The low-profile cushioning platform also has a 4-mm heel-to-toe drop. This construction allows the wearer to feel planted to the ground and feel stable during dynamic movements.
Protecting the top of the foot from outside elements is the open weave mesh upper. This material is soft and pliable, allowing the foot to move. It is also breathable and keeps the foot chamber well-ventilated.
The upper is reinforced with the Duracage which is made of polyurethane (PU), a type of plastic that is sturdy. It creates a wrap that protects the quarters during rope climbs. It extends to the back of the shoe, creating a heel cup to keep the rearfoot steady. The Duracage is also seen at the forefoot, forming a toe bumper that protects the toes during burpees.
The lacing system at the midfoot integrates with the Duracage. When the laces are cinched, the lateral structures are drawn in, amplifying the support for side-to-side movements.
Further securing the locked-down fit is the plush tongue and collar. The tongue evenly distributes the pressure created by the laces to keep the foot comfortable and secure inside the shoe. As for the collar, not only does it prevent chafing at the Achilles, but also prevents the back of the foot from sliding out while training.
