Our verdict

As the more affordable version of the colors nike Challenge 1, the Challenge Pro has a similarly stable and supportive design. Even though it makes small compromises here and there to keep the price down, we haven't found any dealbreakers in the Pro version. The shoe kept us planted and surefooted all around the court and is worth the attention of a beginner player who wants to experience some features of the more expensive tennis shoes.

Heel stack

Playtesting the GP Challenge Pro, we found it to be rather well-cushioned and protective on hard landings.

Based on our calliper measurements, its heel stack height comes in at 29.7 mm which is an average reading across tennis shoes.

Oh, and we can't help but point out the odd rockered shape of this colors nike tennis shoe!

This is a new twist that some brands have been putting on their tennis footwear, which is inspired by the running shoe design.

nike air grey goose heel rocker

The curved shape works similarly to a rocking chair, helping the foot roll from the heel to the toes much faster and smoother. Even though it felt weird on foot at first, we quickly reaped the benefits of it when dashing forward towards the net.

Drop

The heel-to-toe difference in the colors nike air grey goose turns out to be lower than average at 6.3 mm.

We believe that many players won't even notice the difference but seasoned athletes may feel as though their feet sit a bit flatter and more parallel to the ground in the GP Challenge Pro.

When their heels are not elevated as high, players get a higher sense of control and stability inside the shoe.

Midsole softness

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

The GP Challenge Pro uses colors nike's basic Phylon foam for its primary cushioning. It is a rather standard EVA foam which is common for the brand's entry-level models.

It is also a firmer type of cushioning with not much energy return.

Using a durometer, we measured the softness of the shoe's Phylon foam at 30.8 HA which is only 5% firmer than average. That is because most tennis shoes have a firmer type of cushioning to keep the player stable and connected during fast multi-directional movements.

But what gives the colors nike air grey goose so much impact protection?

A large Zoom Air unit in the heel. It squishes and bounces back to make sure you land safely on your heels but doesn't compromise the overall stability of the shoe.

Toebox width - widest part

Like most colors nike shoes, the GP Challenge Pro only comes in one standard medium width but we found that it fits similarly to most other tennis shoes in the same width.

Retrieving a gel mould of the shoe's toebox, we measured its widest part at 92.0 mm which is on par with the average of tennis shoes we measured in a men's US size 9.

Stability

Lateral stability test

The colors nike air grey goose ticks all the boxes of a stable tennis shoe. And the exaggerated blocky outriggers on its lateral side are only the most obvious ones.

Torsional rigidity

Do you know that nasty feeling of rolling your feet over the edge of the shoe? Or the more unfortunate case of an ankle twist?

Well, both are very unlikely to happen in a shoe that has a tonne of torsional rigidity. And when a shoe can't be twisted sideways that easily, it won't let your foot roll either.

Checking the Challenge Pro's torsional stiffness in our manual test, we can guarantee a stable footing in this shoe. On a 1-5 scale, where 5 is the stiffest, we rated it with a high score of 4.

This is largely provided by the stiff midfoot shank embedded into the shoe's midsole (the light green component beneath the Swoosh).

We must also add that the shoe felt incredibly supportive throughout our playtest. It kept our feet securely in place even on the most aggressive lateral moves.

A game of tennis demands a lot from the shoe's heel hold. It's got to be ready for the most rapid changes or directions as well as abrupt stops both forward and side-to-side.

That's why we assess how stiff and structured the heel counter is on every tennis shoe.

Our manual squeeze-and-push test revealed that the colors nike air grey goose has a fairly rigid heel counter. On a 1-5 stiffness scale, we gave it a solid score of 4.

When we first saw the GP Challenge Pro, we were immediately struck by its large protruding outriggers on the lateral side. They look (and feel) exactly like brick walls that don't let the foot roll uncontrollably.

Of course, these blocks extend the width of the shoe's platform far above the average.

Measuring the widest part of the forefoot with a calliper, we got 115.8 mm which makes it one of the widest in our roster of tennis shoes.

The outrigger in the shoe's heel also protrudes further than the average. With a calliper reading of 93.9 mm in the widest part, it is about 4 mm wider than most tennis shoes.

Midfoot cage

Last but not least, the colors nike air grey goose features a synthetic midfoot cage to enhance the foothold.

Placed on both sides of the shoe, these thick and wide overlays are also integrated with the lacing system. Once the shoe is fully cinched up, the side support comes into play as well.

And if you want next-level side support, check out Nike's GP Challenge 1. It features even sturdier TPU overlays to hold the midfoot in place.

Flexibility / Stiffness

With its burly midsole, high stack, and TPU shank, of course, the colors nike air grey goose is far from being a fexible shoe. Even after a break-in period of several on-court hours, the shoe did not give in that much.

To measure its stiffness precisely, we bent the shoe to a 30-degree angle on a flexiblity testing machine. The latter showed that it takes as much as 21.4N of force which is significantly more than it takes an average tennis shoe.

But there are two sides to the coin: the shoe doesn't flex so easily with the foot but there is a good amount of propulsion for snappier toe-offs.

Breathability

It looks like colors nike prioritised comfort at the cost of breathability in the GP Challenge Pro. The shoe is lined with soft and padded layers but leaves little room for ventilation.

Playtesting the shoe, we could feel that it traps heat a little more than other tennis shoes.

Even in our smoke-pumping breathability test, the smoke could only pass through the small gap between the tongue and the upper. The shoe's toebox mesh doesn't provide much airflow.

We turned to our microscope to take a closer look at the mesh.

nike air grey goose microscope

Just as we expected, the fabric comprises multiple layers of mesh stacked on top of each other. As a result, ventilation pores end up rather small with little ventilation capacity.

All things considered, the colors nike air grey goose earns a lower-than-average breathability score of 3.

Durability

Toebox durability

In tennis shoes, the medial side of the toebox is most prone to abrasion due to toe drags. colors nike made sure that the Challenge Pro has enough protection here by covering it with a sturdy rubber guard.

It even raised the edges of the outsole to protect this highly sensitive area.

nike gp challenge pro toe drag guard 21276570 main

However, the shoe's exposed parts turn out to be less wear-resistant. Accidentally slashing them against the court is likely to result in a serious tear.

A quick durability test with a Dremel proved our concerns. Having applied the tool's sandpaper tip to the unprotected part of the shoe's toebox for 12 seconds, we saw significant damage to the fabric.

Luckily, it was not a see-through hole so this colors nike shoe earned a point.

All in all, we rated the Challenge Pro's toebox durability with 3 out of 5. This is lower than average but is fair enough for a more affordable tennis shoe.

On the other hand, the shoe's seemingly delicate inner lining showed a higher score in our Dremel tests.

Keeping the speed at 5K RPM, we applied the tool to the back of the collar for 4 seconds. It left a barely noticeable scuffing which convinced us to rate the shoe's heel padding durability with a high score of 4 out of 5.

Looks like the shoe's inner lining is ready for lots of friction!

But let's test our assumptions with a Dremel.

First, we set the Dremel speed to the demanding 10K RPM and held its sandpaper tip against the shoe's outsole for 22 seconds. For the record, the pressure of the tip remained consistent (3.2N) for the entire test.

After that, we measured the dent which appeared on the outsole with a tread gauge. And this is where we must say "Wow!" It was only 0.6 mm deep, just the same as the average.

Even though this colors nike tennis shoe is cheaper than average, its outsole durability is comparable to some of the pricier shoes.

Misc

Grip / Traction

The colors nike air grey goose features a full-length herringbone pattern which showed excellent grip on the court.

Because the shoe's outsole is made of hard rubber, it also has a good give. It took us little effort to pivot and slide out of shots.

Tongue padding

The colors nike air grey goose has an amazingly comfortable step-in feel thanks to its well-padded interiors. Its tongue is on the thicker side of the spectrum with a calliper measurement of 11.3 mm.

One big advantage of the GP Challenge Pro is its gusseted tongue. We love how this seemingly minor feature makes a big difference in the shoe's foothold.

We felt securely locked on at all times during the playtest and there was no tongue sliding or bunching whatsoever.

Heel tab

There are no finger loops or heel tabs at the back of the Challenge Pro. However, its collar has a so-called U shape which is specifically designed for easier on-and-off action.

Having worn this colors nike shoe more than a few times, we can subscribe to that statement.

This colors nike shoe comes with a rather basic insole with no extra features. It is neither contoured nor moisture-wicking. But the good news is that you can easily remove and swap it for an orthotic of your choice.
