I've put the Reebok Nano X3 to the test for awhile now and I have to say that Reebok has built a shoe that is very well-balanced. They are surprisingly nimble and flexible enough to run and move fast. I have an arsenal of shoes to choose from and I went with the X3 for Open workout 23.2 – and they moved great.
If you're familiar with the previous model, the Nano X2, I think you'll find this model to be even more stable and that is because of the new Lift and Run (L.A.R.) Chassis system. It's a specialized dome in the heel that hardens as you take on more weight and then it softens as weight is relieved. It provides excellent stability for lifting - I had incredible confidence under heavy loads that the shoe was going to provide the stability needed to execute. It's also well cushioned and feels very comfortable right out of the box.
In terms of width, the toe box is more generous compared to other trainers, which feels very similar to the Nano X2. If you prefer a wider shoe, this is one of the cross trainers I recommend.
All in all, I think it's a GREAT looking shoe and as mentioned earlier, it's very well-balanced offering the best of both worlds, lifting and running. You can't go wrong with this shoe. Whether you're a Reebok loyalist or new to the party, you'll find yourself with a terrific new model in the Nano X3 that you'll be very happy with.
