The Japanese are at the forefront of technological research, but they are still a very traditionalist people. And the Nimbus is a shoe that evolves, over time, into the materials it is made of, maintaining that cushioning shoe setting that offers a high degree of stability.
The Asics Nimbus is a shoe aimed at running over long distances, to support the athletic gesture with less comfort, even less efficient than non-evolved athletes, even heavy ones.
And he does it very well, even if his way of doing it is very different from what has become the modern cushioning standards offered by most brands.
The upper of the Aicss Nimbus 22 is made with a 3d mesh fabric that has well-perforated areas alternating with other more substantial ones that serve to strengthen a structure without reinforcement layers, if not those of the Asics logo, located on the medial side, which are involved in the lacing system.
The fabric is very malleable, although not stretchy.
The forefoot area is shaped in such a way as to dress on the upper part of the foot without almost touching it.
At the beginning I was a little perplexed by this feature, not feeling compression around the fingers, and I doubted the ability of the shoe to keep the foot during the race ..
Fortunately, the medial area is very well profiled, with the fabric that supports the internal medial part of the foot, and the lacing system crushes it against the shoe, without the laces causing any discomfort, thanks to a very well padded tongue that manages to blend perfectly with the upper, to create the feeling that the foot is wrapped in a single continuous layer of fabric.
Even the collar and the very rigid and stabilizing heel counter are very well padded, at a level that no other shoe on the market can compare, and they comfortably and stably wrap the heel.
The rear tongue, due to these padding, is very tapered, to the point of suggesting that it can create annoying pressure on the tendon. But it is not so, the abundant paddings manage to totally wrap it up, without causing nuisance
As tradition, the midsole of the Asics Nimbus 22 has a material structure – in this case the FlyteFoam – in which Gel cushions are inserted under the heel and under the phalanges.
In the medial area, there is the classic plastic support arch, the so-called Trusttic.
The structure has a thickness of 30mm at the heel, and 20mm at the forefoot, which is well suited to a “rolled” step.
Still, it appears that the toes are resting in a higher position, so much they are not loaded as would be expected in a shoe with a high heel-toe differential. Probably this is due to the medial structure that manages to make the load dissipate on itself, just as it happens in architecture in the supporting arches.
The impact zone of the Asics Nimbus 22 midsole, like all previous Nimbus, is devoid of the typical external bevel present in many other running shoes. Bevel which ideally should allow a better landing moment, making the movement of the roll more fluid.
The midsole is not even equipped with a “rocker” that favors the heel-toe pendulum movement.
If it weren’t for the lack of midsole in the internal medial part where the Trusstic is located, the Nimbus 22 would be an “iron”, because in the end the rubber of which it is composed is not even spongy, but rather has its own certain firmly.
Thanks to this the shoe provides a very stable ground contact.
In Nimbus 22, it is not the midsole that cushions against the ground, but the foot that receives the beneficial effects of the internal structure of the midsole.
Starting to move, even just walking, at the moment of resting on the ground, there is a very concrete support of the shoe, but also a high degree of compression under the heel.
It is a gradual compression, measured, not cushy, but very very “satisfying”, and very very stable. It makes you understand immediately that with this shoe you can run very comfortably, without trauma.
During the rolling of the foot, the action of the Trusstic medial arch is felt supporting the foot, which almost seems to suspend the foot from the ground, preventing the weight from loading on the midsole. A kind of pressure is felt coming from below under the arch of the foot, in the part where the phalanges begin, as if to push the movement of the foot.
During the race, even at low speed, it seems that you no longer perceive the compression moment of the midsole under the heel; the impact on the ground is absorbed without sponginess, the fall of the body weight is absorbed without causing the foot to sink, and the roll also slips with a certain thrust that helps the foot not to be loaded with the body weight and the force of the thrust on the phalanges, which work without fatigue.
The moment of the push is supported by the flexibility of the midsole, which has, on the support plant, several grooves that increase its ability to follow the movement of the foot.
The Asics Nimbus 22 is certainly not the shoe with which to push under 5 ‘/ km, but at low speeds it can facilitate the dynamics of the race, to lighten the work of the foot, ankle, knees, thus allowing the body less effort “Passive”, leaving the legs well rested even after long journeys.
Therefore excellent for runners, even those who are not advanced, and who start running to lose kg: the same reason I met the Nimbus 10 years ago … While the most advanced athletes used them and still use them to run 100 and more km with a calm pace but “light”.
