Nike Zoom Rival Fly 4 Review: Daily Use to Race Day

Among Nike’s serious running shoe lineup, the Rival Fly series is the best value you’ll find. As of June 2025, the line has reached its fourth generation and remains a popular pick.

If you’re a student athlete or a runner trying to keep shoe costs down, the Rival Fly 4 is probably already on your radar.

I don’t specifically hunt for budget shoes, but a no-frills shoe with just the essentials is sometimes exactly what works best, and I’ll pick one up on purpose for that reason. This time, I bought the Rival Fly 4 as a no-worries jogging shoe I could grab even in bad weather.

In this review, I’ll go through the fit, sizing, and ride feel in detail — enough to help you decide whether the Rival Fly 4 is worth buying.

Why I Bought the Rival Fly 4

In my mind, Nike’s Rival Fly series and ASICS’ HYPER SPEED series are the two heavyweights when it comes to affordable shoes that still cover the basics well.

I’d never actually worn the Rival Fly line myself — up to this point I’d always reached for the ASICS HYPER SPEED.

There wasn’t really a specific reason I’d stuck with the HYPER SPEED. It’s just what I bought first, so I never had a reason to switch.

I used the HYPER SPEED for easy jogs, moderate-pace runs, and sometimes even long runs. There’s no real propulsive assist and the cushioning is middle-of-the-road, but I actually liked that — the moderate assist and cushioning felt comfortable and easy to run in.

The one drawback with the HYPER SPEED was grip. On rainy days or wet pavement after rain, it would slip, which made it a hassle to use.

When I looked into the Rival Fly 4, other reviewers mentioned strong grip. If it could match the HYPER SPEED on price while beating it on grip, I figured the Rival Fly 4 would be the better call.

My only jogging shoe lately has been the NOVABLAST 5, and its cushioning felt like a bit much for that use. I wanted something with a more classic ride, like the HYPER SPEED or Rival Fly.

So this time, I decided to pick up the Nike Rival Fly 4.

Ride Review

Here’s what I ran in the Rival Fly 4 for:

Starting with an easy pace, my first impression was — put negatively, unremarkable; put positively, a shoe that lets your foot land naturally without getting in the way. The cushioning isn’t quite low-stack territory, but you feel the ground directly.

Even at an easy 8:51/mile, nothing felt off. I normally use the NOVABLAST 5 as my easy-jog shoe, but for a natural foot-strike, the Rival Fly actually feels smoother.

That said, the direct ground feel starts to wear on you the longer you jog. It might not be the right shoe for long, slow jogs.

I picked up the pace to around 7:15–6:26/mile, which for me counts as a faster jog, or moderate pace.

At this faster jog pace, it takes a bit more effort. It’s still on the same spectrum as jogging, but hitting a moderate pace means consciously deciding to run faster.

There’s almost no propulsive feel from the Rival Fly 4. Nearly all the forward drive after landing has to come from your own legs. There’s zero bounce, so runners who mostly wear max-stack shoes might even feel like this one “doesn’t go.”

For me, though, that no-frills character is exactly what feels good. It’s easy to focus on carrying your foot forward horizontally to move efficiently, and turnover comes easily — it reminds you what proper distance-running form actually feels like.

Picking up the speed doesn’t change the ground feel much, but the response between landing and feeling the ground underfoot is quick. The cushioning is moderate in the best sense.

I never really planned on running at 4:50–6:26/mile (3:00–4:00/km) pace in the Rival Fly 4, so I haven’t tested it there yet.

Finally, I ran some strides under 4:50/mile. I usually run five strides as a warm-up before a key session, at roughly that pace.

The faster I went, the less that lack of propulsive feel bothered me. At higher speeds, even max-stack shoes stop giving you that bouncy, assisted sensation, so a shoe like the Rival Fly that lets your legs turn over freely actually suits the faster end of the speed range.

I finished the strides very smoothly. The pace was on par with other shoes, and the effort felt about the same too.

Bounce, Propulsion, Stability, and Fit

Here’s a summary of what it’s like to run in the Rival Fly 4.

I don’t think you should go in expecting anything special from the Rival Fly 4. It’s priced within reach of student athletes, and it’s a shoe built around cost over cutting-edge features.

There’s nothing special about the bounce or propulsion — both are strictly conventional, and you’re doing the propelling yourself. There’s reportedly a Zoom Air unit in the forefoot, but I never felt it at landing.

The shoe itself is quite stable. The midsole is reportedly around 30mm thick, and the cushioning has enough firmness that your foot doesn’t wobble side to side at landing.

I found the fit to be good. The upper material is soft, and there’s no awkwardness when you slip your foot in. That said, there’s no wide-fit version, and the shoe runs on the narrower side, so runners with wide feet might find it a bit tight.

Look and Build

Here’s a look at the Rival Fly 4.

The tongue is on the thin side. The heel material, on the other hand, is thicker than I expected — though not so much that it feels bulky.

The upper material feels soft to the touch and comfortable against your foot. There’s no stiff or scratchy feeling, and it flexes plenty.

Flip the shoe over and you’ll see a cutout in the middle of the outsole, revealing a fairly soft plate underneath.

Sizing

I bought a US 9.5 (27.5cm) Rival Fly 4. My actual measured foot length is 27.0cm, and the 27.5cm fit true to size.

Even with slightly thicker socks, I had about half a thumb’s width of room at the toe. The 27.5cm runs a touch long. The width, on the other hand, is on the narrow side, giving the shoe a slim, elongated feel.

Here’s my actual foot size for reference:

With thick winter socks, plenty of shoes feel cramped at 27.5cm, but the Rival Fly 4 still had some breathing room. You don’t need to size down — your usual size should work fine.

Runners with wider feet might find it snug. Keep in mind there’s no wide-fit version available.

Weight

I measured my US 9.5 (27.5cm) pair at 244g — heavier than I expected.

That said, you don’t notice the weight while actually running. It feels like the weight you need to keep a baseline level of cushioning.

Grip

Grip is the biggest question mark with any Nike shoe, in my experience — I’ve yet to come across a Nike model with genuinely strong traction.

Here’s what the Rival Fly 4’s outsole looks like.

I actually ran on wet pavement. My take: for a Nike shoe, the grip feels somewhat improved — but it still slips.

Outsoles that genuinely don’t slip on wet roads include ASICS’ ASICSGRIP and Adidas’ Continental rubber. Compared to those, the Rival Fly 4’s grip falls short.

Durability

I’ll keep updating this section as I put more miles on the shoe. The upper is very thin, and the midsole stays light despite its thickness, so my expectation is that overall durability will be on the low side.

Fresh Out of the Box

Midsole condition:

Outsole condition:

At 350km

The Rival Fly 4 has now logged 350km. The midsole was already on the thin side to begin with, but it’s compressed further since day one — landings feel firmer against the ground now.

That said, it still looks like it has plenty of life left.

Since I’ve mostly used the Rival Fly 4 for easy jogs, the outsole hasn’t worn down much. Grip was already modest to begin with, so I haven’t noticed any further loss of traction from outsole wear.

At 410km

The midsole has developed noticeable creasing by this point. The ride feels a bit firmer at landing.

The outsole has worn down a fair amount too.

At this point, I passed the pair along to someone else.

Who the Rival Fly 4 Is For

The Rival Fly 4 is a good fit if you’re one of the following:

As I mentioned earlier, don’t go in expecting anything special from the Rival Fly 4’s performance. After discounts, it typically sells for around ¥6,000–7,000, which makes it an outstanding value.

Shoes with a similar midsole thickness but more advanced features include Adidas’ Takumi Sen and the Brooks Hyperion series, but the Rival Fly 4 is dramatically cheaper and easier to justify buying.

On its own merits, the Rival Fly 4 performs well — it doesn’t feel like a ¥6,000–7,000 shoe.

In my personal opinion, a moderate-stack shoe like the Rival Fly that lets you land naturally is a better fit for beginners than reaching for an unnecessarily thick shoe.

How I Plan to Use It

Here’s how I plan to use the Rival Fly 4 going forward:

It handles everything from easy jogs to faster jogs without issue. That said, the firmness at landing starts to add up the longer you run, so it’s better suited to shorter jogs — roughly 30 to 60 minutes.

For anything at marathon pace or faster, I reach for a different shoe — mainly because I own other pairs that are better suited to that kind of work.

For rep-pace work (around 1500m race pace) and hill sprints, though, the direct ground feel and quick response feel like a good match, so I’m planning to use it actively for those sessions.

That said, if the Rival Fly 4 were the only shoe you owned, it would hold up fine even for tempo runs.
