Our verdict

Marketed as ASICS' most advanced tennis shoe yet, we can attest that the Court FF 3 lives up to that claim! As our playtests and lab results show, it is a highly stable, locked-in shoe that is perfect for aggressive players who dash from end-to-end to secure points. Not to mention that the Court FF 3 will outlast many other tennis shoes out there in durability!

Who should NOT buy

The Court FF 3 is one of the priciest tennis shoes on the market. But the good news is that you can get equal quality and performance from a shoe with a cheaper price tag, such as ASICS Gel Resolution 9.

Also, the shoe's one-piece Mono-Sock upper is not for everyone. Particularly not for players with wide feet. These folks can turn to the aforementioned Resolution 9 or the ASICS Gel Challenger 14.

Cushioning

Shock absorption

New

The higher stack of this premium ASICS shoe offered a very reliable underfoot cushioning, especially in the forefoot area.

With its unusually high shock absorption measurement of 77 SA in the ball of the foot area, our toe joints could feel the added impact protection during springs and jump shots.

The Court FF 3's heel, on the other hand, returned just a normal reading of 100 SA.

Energy return

New

As a stability and baseline-oriented tennis shoe, the Court FF 3 prioritizes plantedness over propulsion and bounce. Its grounded feel was reflected in our below-average energy return measurements of 42.1% in the heel and 42.5% in the forefoot.

Heel stack

Based on our caliper measurement, the Court FF 3's heel stack height comes in at 32.2 mm which is among the thickest we've seen! Undercut only by the Resolution 9 (32.5 mm) and the Mizuno Wave Enforce Tour (33.0 mm).

The difference in stack height between the shoe's heel and toes comes at 10.4 mm in the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021.

This is a fairly average drop for a tennis shoe which puts the foot in an optimal position for heel landings as well as fast and smooth heel-to-toe transitions.

Midsole softness

Note: a low durometer measurement equals a soft material, whereas a high measurement means it's firm.

ASICS uses its premium FlyteFoam cushioning in the Court FF 3. It is a dual-density setup with a firmer full-length component and a softer piece under the heel.

Using a durometer, we measured the shoe's primary foam at 31.5 HA which is generally the same as the average. In our playtest, it felt moderately firm and quite responsive.

Getting the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021, be prepared for a pretty snug, one-to-one fit. We felt like the shoe didn't provide enough space for our medium-width feet.

Applying our caliper to the widest part of the shoe's gel mold, we found that it wasn't as narrow as we expected at 92.2 mm. In fact, it is the same as the average! So it's the tapered toebox shape that contributes to the tightness.

Traction / Grip

Outsole design

New

Elite is the one word to describe the grip on the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021. We felt 100% surefooted during the playtest.

In our playtest, the shoe delivered excellent stopping power, slid when we needed it, and was capable of gripping the court at any awkward angle we found our feet in.

Flexibility / Stiffness

The presence of a shank and a sturdy hard shell upper surely affected the Court FF 3's stiffness. And it is in fact one of the most rigid tennis shoes we tested.

Relying on a shoe flexing tester, we measured the amount of force it takes to bend this ASICS shoe by 30 degrees and it took as much as 24.2N! That's what makes it one of the go-to tennis shoes for baseline players who rely heavily on that side-to-side-support.

ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 Flexibility / Stiffness

Our only gripe with this ASICS shoe is that it looks a little funky in a bent position as the upper material bunches up. But it doesn't affect comfort or performance and we would describe it as merely cosmetic.

Weight

Given the shoe's focus on stability and cushioning, it is not really intended as a lightweight and nimble speedster. Thus, we didn't really expect it to show low numbers on the scale.

ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 weight test

At 14.3 oz (406g), it is an ounce heavier than the average tennis shoe. However, it is still in line with its stability counterparts like the ASICS Gel Resolution 9 and the Adidas Barricade.

For a baseline-oriented shoe, we never felt bogged down by the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021.

Breathability

We were excited to see larger ventilation pores on the tongue of the Court FF 3. But do they beat the already breathable Court FF 2?

Unfortunately, no. The third version took a step back on breathability.

This ASICS shoe didn't feel particularly airy during our playtest and didn't show the best results in our breathability test either. Pumping its upper with smoke, none of it passed through the toebox, whereas the mesh tongue showed only a mediocre result.

But because it's not entirely hopeless, we gave it an average rating of 3 out of 5. In our transparency test below, it is very clear that the shoe's tongue plays the lead role in the shoe's breathability game.

But it just can't pull out the whole shoe's ventilation all by itself. The polyurethane hard shell on the upper doesn't leave much breathing room.

ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 microscope

Taking a closer look at the shoe's toebox through our microscope, we can see a mesh layer beneath the polyurethane. But it's quite densely woven and doesn't look like it could help the shoe's airflow that much.

Stability

Lateral stability test

The ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 must be on your radar if you're after exceptional stability in a tennis shoe.

Our ankles felt steady and supported all throughout the game. Be it aggressive lateral slides, crossover steps, or rapid changes of direction, we never felt at risk of rolling or twisting.

You can see how well-contained our ankle is when we try to shift it sideways in the video below.

Torsional rigidity

The core component of the Court FF 3's stability is the brand's proprietary TWISTRUSS system. Made of stiff TPU, it wraps around the shoe's midfoot and creates a very steady carcass.

ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 twistruss

We twisted the shoe in our manual test and it turned out to be practically impossible. On a stiffness scale from 1 to 5, we rated this shoe's torsional rigidity with the highest 5.

No matter how dynamic our footwork got, this rigid system offered a very secure hold that successfully prevented any awkward wobbles. We also felt like it added an extra kick and propulsion to our moves, acting like a springboard.

Heel counter stiffness

Our heels and ankles also felt at ease courtesy of the shoe's stiff and supportive heel counter. We felt as though our rearfoot got sucked into the shoe's heel cup and secured inside its structured yet padded confines.

If we have to put a number on it, we rated the shoe's heel counter stiffness with a high score of 4 out of 5.

Midsole width - forefoot

Of course, the shoe's stability wouldn't be complete without a wide platform to rely on. And the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 takes good care of that.

We've got extended contact points with the ground in both the forefoot and the heel. Using our caliper, we found that the widest part of the forefoot measures 114.6 mm which is slightly wider than average.

There is no need to worry about the shoe's softer heel cushioning as it is very well controlled by the wide contact area and the stabilizing shank.

Durability

Toebox durability

Disappointed with the shoe's breathability, we had ZERO doubts about its durability.

The Court FF 3 was built for the most aggressive on-court action, including toe drags and multi-directional slides. Equipped with a Dremel, we challenged the shoe's reinforced toebox for 12 seconds at a 5K RPM speed.

And as you might expect from an elite $170 tennis shoe, this Court FF just laughed at us for this attempt. The tool didn't even go halfway through the hard shell layer! And you can also see how the shoe's protective stripes get even more aggressive and pointy on the inner side of the toebox.

Taking all of this into account, the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 deserves nothing less than the maximum 5 out of 5 for toebox durability!

Heel padding durability

If only we could say the same about the shoe's inner lining...

The material that covers the shoe's heel counter from the inside is made of a pretty delicate textile. It took as little as 4 seconds of Dremel drilling to leave a visible hole in it.

On a 1-5 durability scale, we had to rate the shoe's heel padding with a lower score of 2. Most likely, it will be one of the first parts to give up over time.

Outsole hardness

But when it comes to the outsole, we found that its wear resistance is second to none!

First of all, it has a decent level of hardness for a premium tennis shoe. According to our durometer, it has a reading of 85.3 HC which is standard for a tennis shoe.

We always start with this test to make sure that the shoe's rubber is not dangerously soft and, consequently, fragile.

Outsole durability

Turning to our trusty Dremel, we couldn't help but turn the speed up to 10K RPM and put the Court FF 3 through its paces. We also drilled for a longer period of 22 seconds to really test the outsole's limits.

And the result was absolutely stunning! First of all, you have to really look for the dent, and secondly, our tread gauge shows that it's as shallow as 0.4 mm!

Taking into account the shoe's 6-month outsole warranty, we can wholeheartedly recommend the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 as one of the most durable tennis shoes!

Tongue padding

Assessing the in-shoe padding, we found that the tongue is not particularly thick on the Court FF 3. With a caliper measurement of 5.9 mm, it is slightly thinner than average.

We assume that's because ASICS went for a more one-to-one, sock-like experience in this tennis shoe.

Tongue: gusset type

There is no separate tongue on the ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 as it features a one-piece upper called Mono-Sock. We found that it creates a highly secure foot containment and a very intimate feel with the shoe. Having tested dozens of tennis shoes, we can describe it as one of the most secure uppers.

ASICS Lyte Classic Grey Marathon Running Shoes 1203A168-021 Tongue: gusset type

And if you have narrow feet, you might as well make use of the extra eyelet at the top. You can make a runner's knot to further lock down the foot.

If, on the other hand, you have wide feet, then putting on the shoe can be a real hassle which requires both hands and a bit of time. So, wide footers might want to consider the Resolution 9 instead as it comes in a wide option and a wider shoe mouth.

The lack of a finger loop makes it even trickier to get the shoe's Mono-Sock upper on. We recommend using a shoehorn if you don't want to damage the back of the shoe too soon.
