The L.A.R chassis is essentially designed to give you more responsiveness through the heel when jumping and running, then compress and stabilize as you lift. I think you feel the chassis in action more for the former, and I don’t really notice it when lifting. According to the press release, the heel clip and cup shape also changed, but I didn’t notice much of a difference in my testing thus far. New and improved” is sort of an understatement when it comes to the Nano X3. Thanks to a reworked FlexWeave upper and innovative Lift and Run Chassis System, this latest iteration is quite different from previous profiles. For one, the upper has a more rigid feel to it that doesn’t stretch as much over extended use. This helps create a more secure setup that can keep your feet contained whether just starting a program or wrapping up a routine.

I know, it’s pretty difficult to picture what I mean and I’m not the best at explaining the physical construction piece in writing, so in my review, I’ll be sure to include a picture and clip of the chassis to help give you more context. Comfortable, color scheme, and fit are awesome,” wrote one reviewer. “Great performance and exactly what I needed for cross training.” This shoe’s blend of versatility and stability did well for WODs that blended strength work with things like short runs, double-unders, and box jumps. I liked that even for longer WODs these didn’t get too uncomfortable. Granted, it did take a week or so to get them there. The outsole on the Nano X3 has also been reworked and the consistent rubber outsole with a lug pattern that we saw on the Nano X1 and Nano X2 is no more. The Nano X3’s outsole is fully rubber and features a smoother lug treat patterning.That being said, If you have notably narrow feet and typically feel like you’re swimming in Nanos, then in your case, you may want to size down a half size to play it safe, but I think that will be the only exception in this model.

My only gripe with the Nano X3 for versatile training is that they do take a bit of time to break in which I’ve mentioned already in this article. I would not expect these to feel perfect the first time you wear them and I’d give them a week or two to feel better for this training style. Testing the Reebok Nano X3 for Short Runs and Daily WearThe Flexweave upper is also a positive change about the X3 for athletic-style sessions. I found the upper to hug the foot well and I never had issues sliding in around the toe box in this model as I did in the Nano X2, which I noticed here and there when doing broad jumps. Another major update with the Nano X3 is Reebok’s utilization of their Lift and Run (L.A.R) chassis. This is a feature that is intended to make the midsole a little more versatile regarding its stability and versatility. I have yet to have issues with my shoe’s durability when it comes to rope climbs which is a good sign with the volume that I program climbs. Testing the Reebok Nano X3 for Versatile Training Thanks for such a detailed review! I have the nano X and found them like little ovens on my feet (they’d get SO hot) and quite heavy and clunky for any running based activity (even over 200m or so). How do you think the X3 compares in these regards?

The third thing to like about this model is its Lift And Run (L.A.R) chassis system. It took me a minute to appreciate this feature, but I think it’s a subtle and positive change for the Nano X3. I’ve had multiple athletes reach out about how they miss the 4mm heel-to-toe drop on the older Reebok Nano models and that they don’t like the new higher drop. If you’re in this camp, then you’ll want to pass on the Nano X3 as it still has a higher drop. The main changes from X2 to X3 are the unisex sizing, the L.A.R. Chassis in the midsole, and updated tread pattern. Otherwise, the shoes are pretty much the same—similar upper, similar lacing system, similar tongue, similar rope guard, and similar overall shape. The Nano X3 CrossFit shoes include some new features that set them apart from previous iterations. Namely, the trainers are largely being offered in unisex sizing, with some select women’s-only colorways (in women’s sizing). New this year, the Nano X3s feature a Lift And Run (L.A.R.) Chassis in the midsole. According to a press release from Reebok, this is a “new midsole technology built for stability when lifting and added cushioning for running and jumping.”

Reebok Nano X3 Introduction

With rope climbs, durability can always be variable based on the rope you’re using and the rope climbing style you’re using, but I think most should be safer in this Nano X3 compared to the past two models. If you experience issues, please reach out and let me know. 3. Lift And Run Chassis System Increases Versatility However, that didn’t happen since the replacement pair was too small. I wasn’t able to comfortably run in them, either. I have a question. Do the X3s have arch support? I own the X2s and can’t stand the molded arch support in them. I can’t find a reliable source to verify if the X3s also have them.

They are stable to workout in but they do have a solid cushioning system to last without your feet hurting. I would really like them to lower the price a bit so more people could enjoy them but overall my experience with them were great. Comparing and contrasting gym shoes is sort of my thing, so to see which sneaker slid into the pole position this year, I donned each silhouette for multiple weeks across a number of training disciplines. From free weight lifts like squats and deadlifts to CrossFit-centric movements and plyometrics, varying running routes and more, I put both the Metcon 8s and Nano X3s to the test to see which brand delivered the goods. Outside of training performance, I also noted other key qualities like durability, comfort and (of course) style. In the context of weight training, the Nano X3 provided a nice level of stability when squatting well over three plates and when deadlifting up to 500 lbs. They also did a pretty good job for general strength sessions on machines and with dumbbells.For OG Nano fans who loved the Nano X models and below, I’m not sure you’ll resonate with the Nano X3 as they feel more like the X2. Thank you! I think you’d be safe going true to size in the Nano X3 if you have only a bit of length at the end of your toe box in the 8. If you have more than a thumb’s width, then go down a half-size! The flat, wide base gives you a great platform to weight train. I had multiple sessions of strict strength training and never was disappointed. The Floatride Energy foam gives the forefoot a nice level of bounce and I feel like the L.A.R also adds to this shoe’s springiness and its ability to feel comfortable during landing phases of jumps. The heel compresses a tad in this context, which I like.
