Value meets quality - The Asics Gel Flux 3
Finally, I relented to the purchase of the Asics Gel Flux 3 which has turned out to be one of the better shoe buying decisions I had ever made.
This is a very clean and good looking shoe, well built and without frills, designed for the lighter weight neutral runner.
Some of the materials used to build this shoe are the same as those found in Asics models costing twice as much but with less gel, less padding and less expensive foam.
The overlays were of the traditional stitched variety and nicely done. The Asics Nimbus, on the other hand, is built at a different assembly facility and likely with more care and oversight than a model costing so much less.
The sock liners/inserts of the Nimbus or Kayano are a major upgrade from the less costly models, a great improvement over the simple slab of foam used in the Flux.
In some ways, the Asics Flux is about as good as a shoe needs to be. It's an affordable daily trainer that can and will be for me, a near perfect half marathon training shoe.
But if you go to the expense of entering a marathon with the travel and hotel costs involved, I would get a cheaper hotel and opt for the Cumulus or Nimbus.
I am a mid-foot striker of 148 lbs and if I were a 200-pound heel striker I would opt for the Asics Cumulus, Nimbus or the excellent Asics GT 2000.
The toe box is generous, flex is good, the ride is quiet.
With 150 miles of road running on these shoes I notice no unusual wear, they have the AHAR (ASICS High Abrasive Rubber ) in the heel and regular rubber elsewhere.
The uppers are wearing well.
Due to lack of reflective material I use reflective shoe laces and 3M reflective material on the heel.
Drivers are more distracted than ever, I NEVER assume drivers can see me! I may have to become a trail runner.
I will use these shoes for training, perhaps with inserts from an old pair of Nimbus.
The Asics Gel Flux 3 is the best shoe in this price range, with lots of quality carrying over from the more costly Asics. Quality is remembered long after price is forgotten!

I think this shoe would be amazing for gravel or rough terrain because of the extra cushion and support that the shoe does have.
Updates to Asics Gel Flux 3
- The 3rd version of the Asics Gel Flux gives reliable cushioning that’s ready to tackle the asphalt. The platform itself is smooth and comfortable. Breathability and security are handled with grace by the upper unit’s open mesh & synthetic overlays, while the outsole is as protective and durable as ever with its high-quality rubber materials.
- Some of the components in the mid-sole are present in order to give the runner a more efficient gait. Transitions from the heel to the toe are much smoother because of a specific unit that guides the stride. The structural integrity of the shoe is also preserved by a lightweight, but sturdy system in the mid-foot section.
- Impact protection is a helpful feature that gives the runner more confidence when traversing the ground. Landings don’t become worrisome and discomfort isn’t felt during this phase in the running cycle. The Asics Gel Flux 3 has a cushioning unit that is able to efficiently protect the foot from impact and shock.
- The robust outsole unit of this running shoe uses two separate compounds that have a specific purpose. The heel area features a compound that is very durable and defensive against wear and abrasion. The forefoot area uses a more responsive rubber that gives additional cushioning during toe-off. Both of these compounds deliver responsible traction over the roads.
Asics Gel Flux 3 size and fit
The Asics Gel Flux 3 has a standard running shoe length. The men and women’s sizes follow the regular measurement schemes, so runners can get the right one. The available width is medium, so this shoe can accommodate runners whose feet have regular dimensions. The semi-curved shape allows the natural curvature of the foot to acclimate well to the running shoe when wearing it.
The AHAR® or the Asics High Abrasion Resistant Rubber is a carbon rubber unit that’s primarily placed in the heel section of the Gel Flux 3 and its recent updated version, the Asics Gel Flux 5. It delivers exceptional durability that holds well against abrasion and wear. It also gives traction, so surface control is agreeable and responsive.
The DuraSponge® Outsole is a blown rubber compound that’s placed in the forefoot section. It’s softer and more responsive, so it adds a bit more cushioning and flexibility, especially during the toe-off phase of the gait cycle.
The SpEVA®, which is also used in the popular Asics Gel Cumulus 20's midsole is a full-length foam that gives high quality cushioning and support for the foot. It has a springy nature, so each step benefits from a bit more bounce. It also decreased mid-sole breakdown because of its durable build.
The Gel® Cushioning System is found separately in the heel and forefoot sections of this running shoe. Made from a gel that’s based from silicon, it is able to absorb the shock when landing the foot on the ground. It makes each landing less tasking to the foot of the runner.
A Guidance Line® is a vertical groove that runs along the entire length of the Asics Gel Flux 3. It guides the foot through the gait cycle so that each step becomes more efficient.
The Guidance Trusstic System® is mid-sole support unit that maintains the structure of the shoe and adds torsional rigidity for better transitions.
The upper unit uses open mesh, which is a soft and comfortable material that has an open construction. It delivers breathable and secure coverage at all times. It constantly lets air inside the shoe to keep a cool and dry environment for the foot.
Synthetic Overlays have been stitched onto the main fabric. They provide structure to the upper while also making the fit more customizable by responding to adjustments made with the lacing system.
Additional cushioning is afforded by a Standard Sock Liner. Placed right above the mid-sole unit, this layer makes the platform plusher and more comfortable for the underside of the foot.
