The Nike Streakfly 2 is the Ultimate Speed Weapon: Multi-Tester Review
The Nike Streakfly 2 is Nike's premier 1 mile to 5k road and cross-country racing shoe designed to be the ultimate speed weapon. Priced at $180, it competes with shoes like the Adidas Takumi Sen ($180) and Hoka Cielo Road ($160). Our team at Supwell put the Streakfly 2 through the paces and detail the results and our impressions below.
This is a multi-tester review of the Nike Streakfly 2 from the perspective of several members of the Supwell team. We will be posting first run reviews in addition to the YouTube videos and follow-up articles about how the shoes hold up over the miles.

Background
First released in 2022, the original Streakfly was Nike’s answer to a 5k and 10k racing shoe—but it ended up being too soft and not rigid enough to truly shine on race day. With the release of the Streakfly 2 in 2025, we’re getting a completely different experience. This new version is 1.6 ounces lighter than its predecessor and built with a full slab of 100% PEBA ZoomX foam. It also features a full-length carbon-fiber Flyplate—an upgrade from the smaller midfoot shank found in the first version—and a waffle-patterned rubber outsole that provides standout traction and a unique, grip-and-rip feel.
Specs
- Weight in Men’s Sample Size 9M: 128 grams
- Stack Height: 26mm in the heel and 22mm in the forefoot
- Heel-to-Toe Drop: 4mm
Fit & Feel
The Streakfly 2 features a beautifully engineered upper, reminiscent of the Vaporfly 4’s. It’s light, breathable, and offers a snug, locked-in feel. Except for Barrett—who recommends going up a half size for wider feet—we all went with our regular sizes, and the fit was perfect—no rubbing or hot spots. It should feel like a slipper or a track spike. We recommend wearing a thinner sock to optimize the fit and feel.
Supwell Team Members
- Grant Reese: Supwell Social Media Manager from Dallas, Texas. I average around 50 miles a week and peak at around 70... for now. I’m currently training for my second full marathon at Grandma’s Marathon 2025 in Duluth, Minnesota, where I’m eyeing a sub-2:50.
- Barrett Reid-Maroney: Supwell Brand Designer from Southwestern Ontario, Canada. I average 65 miles per week, and am in the process of building up to the 70-75 mpw range. My primary training goal is a sub 1:30 half marathon in June 2025 at Forest City Road Races in London, Ontario, but I also have my sights set on a PR of sub 18:30 in my favorite race distance—the 5k.
- Meredith Johnston: Supwell Content Manager from Charlotte, North Carolna. I average 60-65 miles per week. My primary training goal is a sub 1:45 half marathon in the Fall of 2025 and a sub 21:00 5k in November 2025.
Grant: I tested the Streakfly 2 on a 9 mile workout that consisted of 6 x 1-mile repeats (at a 5:40 min/mile pace) with 2 minute walk/rests. This shoe is an absolute WEAPON. I called the Metaspeed Sky Paris a race weapon but the Streakfly 2 is built for pure speed. I was able to clip off my splits all between 5:38-5:42, which was a huge win. This shoe throws you to your forefoot and wants you to stay there. It’s a track spike built for the roads. The only knock, as Yowana mentioned, is the absolute WORK it puts on your calves. After rep 3 and during reps 4, 5, and 6, I was in some hard pain.
This shoe does not want to let you land anywhere near the heel, which obviously felt different for me as a heel/midfoot striker. I wish that I had switched out of the Streakfly 2 for the cooldown miles because it became almost torture. The shoe is still a beast and will be my go-to racer when it’s time to throw down in short races. I’m not sure I’ll use this shoe again in a midweek workout just because of the soreness I know will be lingering in my calves over the next few days. If I race another 5k and MAYBE a 10k, these weapons will come off the shelves and get put to work. They had me gliding at 5:40 min/mile pace and feeling like I had amazing form.

Barrett: For context, I’m 5’10, 160 lbs, and have a high cadence mid/forefoot strike at all paces. My current short distance race paces are in the 6:00 min/mile range and below. I ran a 5k PR on April 2025 in 18:38 minutes, and typically do interval repeats between 5:15-5:45 min/mile in my track style workouts.
The first workout I did in the Streakfly 2 was relatively low volume: I did a warmup in the EVO SL, and then switched into the Streakfly 2 for 8 x 400m @ 5:30 min/mile and below and 2 x 1km at around 5k pace. When I did my first 400m rep around the track, I immediately thought the shoe might be too minimal for me—historically, I’ve preferred shoes with high levels of cushion/bounce such as the Alphafly 3 and Cielo X1 for fast running over stripped-down, lightweight speed shoes, so the intense ground feel of the Streakfly 2 threw me off at first and shook my confidence.
As I settled into the reps, however, the shoe felt more and more natural for my stride and I was able to progressively ramp up my speed for each repeat. Even on tired legs, the Streakfly 2 helped me set a new 400m PR on the final rep (4:46/min mile pace) without putting down what I felt was my maximum effort. For the 1k reps, the shoe also performed well, but I felt myself wishing I had more protection under the forefoot—I love it for the fastest of the fast speed, but for anything longer than a few minutes of intense effort I would still go for the Metaspeed Sky Paris.

The Streakfly 2 possesses what I would call exceptional physical speed assistance—it has an incredibly aggressive rocker geometry, tacky rubber in the forefoot that bites into the track, a thin slab of propulsive ZoomX, and a ridiculously lightweight on-foot feel. What it doesn’t have for me, however, is mental speed assistance. When I lace up the Alphafly 3 or the Metaspeed Sky Paris for a fast effort, it’s as if the shoes are saying “don’t worry, I’ll help you get through this” due to the extra level of pop and bounce they provide. On the other hand, the Streakfly 2 isn’t quite so reassuring—it helps you access an extra gear of speed, but it doesn’t feel like it’s doing the work for you. That being said, there is a refreshing quality to the ride experience that was very playful and enjoyable. This shoe provides a really nice counterpoint to high stack racing shoes, enabling a rate of efficient turnover that feels freeing and natural.
A few other things to note—I’m happy to report that the shoe didn’t aggravate my calves nearly as much as I thought they would after reading other reviews. Your calves certainly feel activated when popping off the forefoot in the shoe, but that didn’t translate into any extra soreness for me in the days following the workout. This might be because my calves are used to bearing the burden of my daily forefoot style of running, meaning I didn’t have to alter my mechanics to utilize the Streakfly 2’s aggressive geometry. Also, if you have a slightly wider foot, I would definitely go up half a size. I did this and the upper is snug and streamlined, yet comfortable.
Meredith: For reference, I’m 5’8”, 120 lbs, and 48 years old. I’m a forefoot striker at all paces, though I’m slower than Yowana, Grant, and Barrett. My easy/recovery pace is usually between 10:00–11:00 min/mile, my 5k workout pace is around 7:20–7:30 min/mile, and my half marathon/marathon pace lands in the 8:00–8:30 min/mile range.
I tested the Streakfly 2 as part of a three-shoe comparison workout, which included 6 x 800 meters at my 5k pace (7:20 min/mile) on a mostly flat section of road. At 131 grams in a men’s size 9.5, it feels insanely light. The geometry is unlike anything else out there—it honestly reminds me of the cross-country flats I raced in during high school. While it supposedly has 26mm of foam in the heel with a 4mm drop, compared to the 361 Miro Nude and Metaspeed Edge Paris, it feels low to the ground—almost like a borderline negative drop.

The ride feels planted and stable. The waffle-patterned outsole provides excellent grip and a clean push-off, which gave me confidence through tight turns and uneven patches of road. The ZoomX foam offers enough protection and snap without being too soft. As a forefoot striker, I felt like the rocker and plate worked with me—not against me—and didn’t overwork my calves. I’d feel confident using it for a 5k or 10k PR attempt, but probably wouldn’t reach for it on anything longer.
Final Thoughts
The Streakfly 2 is a vast improvement over the first version and reminds us of a track spike built for the roads. The almost negative drop geometry requires a strong forefoot strike and running blisteringly fast. It is the type of shoe you bring out only for your fastest reps and pair with a warm-up and cool-down shoe for your slower miles and reps. The ride is reminiscent of a lower-stacked ASICS Metaspeed Sky Paris, combining a perfect use of ZoomX foam with a grippy waffle-patterned outsole rubber and an even more aggressive plate. For us here at Supwell, the Nike Streakfly 2 is a road racing shoe like we’ve never experienced, and we believe it is the premier 800-meter to 5k racing shoe currently on the market. It’s a featherweight Cinderella slipper for those hobby joggers looking to push past their limits and set a new PR in their next mile or 5k race.
