Asics Gel-Flux 5 Review – For the Beginner Runner

Sometimes shoe companies exaggerate the real performance of their sneakers.

They don’t do it on purpose, but they don’t do it on accident either.

Heck, how else are they suppose to stand out among the millions or shoes out there?

Unfortunately good shoes don’t sell themselves.

There’s a very good reason why a shoe company called Saucony has won awards for having the best running shoe no one has ever heard of.

It’s called lack of marketing.

Or in other words, not working as hard as their competitors.

This results in many companies “exaggerating” their claims.

Does the Asics Gel 5 exaggerate do this? Keep reading this review and find out.

At a Glance

Product Name: Asics Gel-Flux 5

Designed for: Daily running

True to size: No (1/2 size too small)

Expected lifespan: 6 – 12 months

Price: $60 – $90

Recommended: Meh

My rating: 4/5

Expect a pretty mediocre shoe if you purchase the Asics Gel-Flux 5. Although it’s not all bad. The midsole is very comfortable with the SpevaFoam, and the outsole reduces weight. It’s a great daily runner especially for newbies, but advanced runners can do much better. I still give it 4 stars due to the comfort, versatility, arch support, sleek design and affordable price tag.

What is the Asics Gel-Flux 5?

The Asics Gel-Flux 5 has accumulated over 500 good reviews on Amazon alone and comes in 6 different colorways.

Its SpevaFoam midsole improves bounce back while decreasing midsole breakdown.

For anyone that doesn’t know, the midsole is breaks down before anything else.

In fact it begins breaking down before it hits the shelves. And that’s with any sneaker.

So it’s good to see that Asics have increased the durability which is going to improve the overall lifespan.

The Guidance Line Midsole provides vertical grooves for better gait efficiency.

The AHAR outsole, which means Asics High Abrasive Rubber, reinforces the weak parts of the outsole for exceptional durability.

The rearfoot GEL technology cushioning system absorbs shock by softening landings and ensuring smooth transitions.

In the outsole lies the DuraSponge technology. It improves cushioning and durability in the forefoot area.

These are all the features of the Asics Gel-Flux 5.

Now lets take a look at the important stuff.

Like whether or not it’s as good as Asics makes it out to be!

The Upper

Asics Gel-Flux 5 Side

The upper includes a breathable fabric in the toe box to keep air flow moving to your feet.

This is an odd design because most running shoes have a full mesh upper for maximum ventilation.

Also the tongue is thicker than usual which provides immense comfort while keeping your feet snug and ankle in place.

The design is similar to other Asics shoes, so nothing drastic in terms of uniqueness, but still does the job nonetheless.

Most of the more advanced features lie in the outsole and midsole, so lets take a closer look at them.

The Midsole

The midsole and outsole are the better parts of the shoe.

In fact that’s why it has “gel” in its name.

It’s similar to Nike’s air heel unit.

It’s a gel cushioning system that provides shock absorption and smooth transitions.

However, one thing I should mention is that this added feature is rendered useless for forefoot strikers.

Those that land heel-first will benefit from it the most.

The midsole also includes SpevaFoam technology and Guidance Line.

One provides bounce back for energy return and the other improves flexibility.

It is then finished with a plush sockliner to keep your feet comfortable for longer.

The Outsole

Asics Gel-Flux 5 Outsole

I love the outsole.

I like any outsole that steers away from the norm.

The Asics Gel-Flux 5 employs an outsole that reinforces areas prone to wear and tear while reducing weight.

It does this by cutting out traction in the middle of the shoe that’s not really needed.

And by putting a high abrasive rubber in the heel and the border.

Performance Review

Considering this shoe is made for running I decided to see how it really performs as a running sneaker.

They include Asics special gel cushioning, a durable outsole, high traction and a comfortable upper.

Customers say they feel like they’re “running on marshmallows”.

Others claim they have an “excellent fit and comfort”.

People use them for daily running, beginner running, road running, pavement running, marathons, half marathons and more.

It’s not hard to find the hundreds of positive feedback and the love that it gets from the community.

Do they perform for running?

It’s a no-brainer.

They’re an entry-level running shoe, otherwise known as something that quickly burns up miles.

They’re not too shabby, but not exciting either.

They’re a cheap running shoe that performs for a solid amount of time.

How long? I’ll discuss that as well.

How Long Do They Last?

They cost around $60 – $90 on

That is an averaged price running shoe.

And in my experience with reviewing average running shoes, there is a lifespan that they all have in common.

A shoe between $50 – $100 will last about a year with casual wear.

Otherwise 6 – 12 months if used for daily running, especially for beginner runners.

Now if you’re an experienced runner that tends to rack up mile after mile, then you’ll burn through these shoes fairly quickly.

Advanced runners will get around 3 – 6 months out of them.

Is that bad and low quality? Not at all, it’s actually pretty average.

Frequently Asked Questions

Are they made for wide feet?

Yes, they have a wide toe box as well as wide size options available.

Are they true to size?

They have a 70% fit rate on Amazon. This is really far from being true to size. Some digging around is needed to see where all the “somewhat small” ratings are coming from.

It seems people have a problem with them being too narrow.

Whether you have wide feet or not, you should size up by 1/2 regardless.

True to size?


Do they have alternative uses?

Yes. Other common uses are general/casual and the gym.

They are flexible and comfortable enough for everyday use.

They also have enough stability and ventilation for intense gym sessions like weightlifting, cardio, running on the treadmill.

How’s the arch support?

Very good. There are reports of them staying comfortable for flat feet, low arch, neutral arch, and even high arch.

Are they good for standing all day?

Unfortunately they are not good for standing for long periods of time.

They are good for walking all day but certainly not standing

I recommend a more sturdier shoe like the Asics Gel Sonoma 4.

Are they lightweight?

Yes. They are fairly lightweight considering all the features and high running performance.

10 ounces makes them a good lightweight running shoe.

My Personal Opinion


If you’re looking for an easy-going running shoe that’s proven to perform, you will enjoy the benefits of the Asics Gel-Flux 5.

They’re affordable and they get the job done.

Plus they’re good for casual/general wear. Examples are high activity jobs like nursing, waiters, dog walking etc.

Are they better for running or casual use?

I say both, as long as you’re a newbie or simply after a comfortable, casual sneaker.

Advanced runners should opt for something far more durable to handle all the extra miles.

If that’s you, go for the Brooks Launch 6 instead.

The Asics Gel-Flux 5 is exactly what Asics says it is and they are not hiding anything.

The Verdict: For Beginner Runners

These shoes offer nothing special but they get the job done for newbie runners.

Advanced runners should stay away from them at all costs.

And so my verdict still stands.

They’re great for beginners or anyone that wants a comfortable sneaker for all day use.
