The Dynaflyte is an exciting new running shoe from Asics! The Dynaflyte is named after Asics’ new midsole material, Flyte foam, which is lighter and softer than standard midsole foams.

The Flytefoam midsole gives the shoe a soft and protective feel of a daily trainer, yet the lightweight design gives the shoe the potential to be an up-tempo trainer or marathon racer.





The Dynaflyte has comfortable, soft woven upper. The piece of woven material has enough structure on its own which makes no overlays necessary.

The woven upper is moderately breathable.
My feet heat up more in the Dynaflyte than in other shoes which caused a blister to form on the ball of my foot on hot days.



The Dynaflyte has a thick, double layer tongue. It does a good job at preventing the laces from creating pressure points on the top of the foot when they are tied very tightly.



Heel Cup

Asics tends to put too much support in their neutral shoes.

Asics wanted to make the Dynaflyte as lightweight as possible, so they were forced to decrease the plastic usage, however, the Dynaflyte still has a very substantial heel cup.

The heel cup spans the entire height of the heel and wraps far around the rear of the foot.


Heel Collar

The heel collar has a comfortable, but not an excessive amount of cushioning. The rest of the heel area does not have any cushioning.

My heel is almost in direct contact with the hard plastic heel cup. Asics does not put any material to cushion the heel cup because they are trying to cut down on weight.

The heel cup is not too uncomfortable, however, I think that Asics has its priorities in the wrong place if they are trying to make a lightweight shoe.

A less substantial heel cup and more cushioning material on the upper would be desirable.

There is a small area of reflective material on the outside of the heel counter.



The Dynaflyte has a standard fit. A wide, accommodating heel and midfoot area and a tapered off toe box.

I can get a good lock down with the laces so that my foot doesn’t slide around in the shoe.



I find that the toe box is slightly uncomfortable. The toe box is curved such that my big toe is forced to bend inwards.

This was both uncomfortable and impractical. The big toe plays a large role in the push off the stage of the gait cycle.

When the big toe is straight, it is as powerful as it can be. Even a little bend in the big toe significantly impacts the power that you can deliver the ground.

Asics should have constructed the shoe with a straighter fit because there is no benefit to a tapered toe box, apart from a more natural look.



The Dynaflyte has a dynamic cushioning system consisting of a layer of gel on top of a thick slab of Asics new Flyte foam.
Flyte foam is an amazing material. Flyte foam is a softer foam compound than standard EVA.

It is  55% lighter than Asics’ other midsole foams, yet it delivers just as much cushioning. Flyte foam is also more responsive than Asics’ other midsole foams.

Durability is also not an issue with the Dynaflyte. I have run 300 miles in my pair of Dynaflytes and they still have plenty of life left in them.

The Dynaflytes’ gel top sole also adds to the soft ride of the shoe.

My foot quickly displaces the gel top sole at foot strike which gives the midsole an even softer feeling. Although the ride is very soft, the midsole does not bottom out like other soft shoes.



The Dynaflyte has an 8-millimeter drop. This is a comfortable amount for both heel strikers and forefoot strikers.

Heel strikers tend to want more drop because it makes their heel to toe transition time faster and because they need more cushion built up underneath the heel than underneath the forefoot.

Forefoot strikers tend to like lower drop shoes because they don’t need heel cushion. The heel cushion adds weight and sometimes impedes their natural running style.



My running form is very different before a race to after the race. I gracefully forefoot strike before a race and sloppily heel strike after a race.

I could very comfortably use this shoe as my warm up and cool down shoe for races.



The outsole is made of strategically placed pods of high abrasion carbon rubber and exposed Flyte foam. There is also a medial post underneath the midfoot which unnecessarily adds support.

The rubber is placed around the perimeter of the heel and in the whole forefoot area. The rubber provides great traction and durability.

The exposed Flyte foam gets pretty beat up. The little stones on the road dent the foam and cause it to wrinkle.

I tried running on trails with the Dynaflyte and the rocks and roots just chipped away at the foam. This does not affect the cushioning much at all.



Asics always likes to sneak extra stability features into neutral shoes.

They cut a groove in the middle of the outsole that spans the length of the shoe, to help correct any bio mechanical imbalances.

Eighty percent of all runners pronate, yet the majority of runners wear neutral shoes.



This groove is a way that Asics helps pronators wearing the Dynaflyte without obstructing true neutral runner.

Since I am a truly neutral runner, I cannot attest to how much support this technology provides.


Best Uses

The Dynaflyte has the soft cushioning of a heavy daily trainer and the weight of an uptempo performance shoe.

I simply used it as any other daily trainer and enjoyed the lightweight feel. I don’t feel like I am missing anything with the reduced weight.

I can also see this shoe being used as an up-tempo trainer or marathon racer for those who like a lightweight shoe with a ton of cushioning.
This shoe is really only for road running; the midsole gets very beat up on trails.



+0.5 indicates that you should buy 0.5 sizes larger in a different shoe; +1 indicates that you should buy 1 size larger in a different shoe.




Asics Dynaflyte vs. Saucony Triumph ISO 3

The Triumph is Saucony’s plush cushioned daily trainer. Both shoes have the same amount of cushioning.

They both have an 8-millimeter drop. The Triumph weighs more than an ounce and a half more than the Dynaflyte.

For that weight, you get a more durable outsole and a heavier, more responsive midsole. The Triumph has a better lacing system which gives the shoe a more secure fit than the Dynaflyte.


Asics Dynaflyte vs Asics Gel Nimbus 19

Asics claims that the Dynaflyte provides the same amount of cushioning to the Nimbus. I think that the Nimbus provides just slightly more cushioning than the Dynaflyte.

The Nimbus is Asics’ built up daily trainer. The Nimbus has more stack height, more outsole rubber, more plastic pieces, more drop and a whole lot more weight.

The Nimbus is a better daily trainer for heavier runners whereas the Dynaflyte is better for lightweight runners. Buy ½ up in the Nimbus.


Asics Dynaflyte vs Altra Torin 3.0

The Torin 3.0 has a very similar ride to the Dynaflyte: Very soft, yet fast.

The difference is that the Torin is only for forefoot strikers whereas the Dynaflyte is suitable for both heel strikers and forefoot strikers.

Unlike the Dynaflyte, Torin’s midsole tends to completely compress before I have finished unloading my landing force into the shoe.

The two shoes have similar weights and similar rubber outsole coverage. The Torin has a comfortable, wide toe box.  The Dynaflyte has a more breathable upper than the Torin.


Asics Dynaflyte vs Hoka Clifton 4

The Clifton 4 has even more soft cushioning than the Dynaflyte. The Clifton is also a faster, more responsive shoe.

The two shoes weigh about the same amount. The Dynaflyte has a more comfortable upper than the Clifton.

The Dynaflyte also has more support than the Clifton. The Clifton has only a 5-millimeter drop, however, the Meta-Rocker technology makes the shoe feel comfortable for heel strikers, just like the Dynaflyte. Buy a ½ size up in the Clifton.

Buy a ½ size up in the Clifton.


Asics Dynaflyte vs Brooks Ghost 10

Both shoes have about the same amount of cushioning, however, the Ghost 10’s cushioning is a little bit firmer than the Dynaflyte.

The Ghost is also about an ounce heavier than the Dynaflyte. The Ghost has a 12-millimeter drop, compared to the 8 in the Dynaflyte.

The two shoes have a similar ride. The Ghost has a more comfortable, secure fit than the Dynaflyte. Buy a ½ size larger in the Ghost.



Asics did a great job making the Dynaflyte! I would like it better if the Dynaflyte had a more breathable upper and a toe box that was less tapered.

I also think that they could decrease the weight a little bit more by getting rid of the medial post and by trimming the heel cup.

This is a neutral shoe after all. The Dynaflyte has the ride and the cushioning properties of a standard daily trainer, yet it weighs more than an ounce less.

The Dynaflyte costs 140 dollars, which is 10 dollars less than the standard $150 for a high-end premium cushioned daily trainer.

These factors make the Dynaflyte a great choice of shoe. After all, why pay more to tie extra weight to your feet?
