Has anyone actually worn the streakfly in a 10k?

Wore them in a 5k and in many 10k tempos. They're great at those distances - better feel for the road.

I wore them in a 10,000m race on the track. Ran a PR. Love them. Very light and responsive. The mid foot shank helps get you into your toe off faster. Easier on turns compared to Next%. I use them for track workouts and 5k-10k races.

I also recorded my highest ever average cadence in them. I can’t attribute that entirely to the shoes, but I believe it was a big factor.

I haven’t tried mine on a track yet, but on the roads, you are better off in Next% unless you are racing something like a road mile. They are super responsive if you are waaay up on your forefoot. Good for doing 400/800 repeats, but not touching the Next% for anything longer.

Basically, if you are on the fence about buying a pair of spikes because you don’t go to the track that often, this is a good compromise because you can crank out fast repeats on the road and they would probably be good on the track too. You can also do longer runs in them, but they aren’t giving you close to the same boost as the Next%.

Similar experience. However, my perceived effort and HRM data showed I was working harder at the same pace than when I’m running in Next%.

The Streakfly ,is a big miss. I returned mine . It doesn’t have the pop I was expecting . I’ll wear my next % for a 10k.

How did your legs feel after the 10K? We’re the super shot or were you able to recover quickly?

I have about 60 miles in mine -- 8 runs. I haven't raced in them yet but if I ran a 5K or 10K I would wear them. I don't have the Next%s, so it's an easy choice.

So far they are the most fun shoe I have run in. I love the lower drop and road feel while still enjoying some cushioning. I would expect to like them better than the Next%s on the track simply due to the lower stack and the torque in the turns.

My legs were naturally sore after a hard effort. Race was on Saturday. Took Sunday off but jumped back into normal training after that. 16 miles Monday. 15 on Tuesday. 14 on Wednesday with a 6 mile tempo built in.

The most compelling anecdotal evidence would come from someone who has both the strekflys and top of line supershoes and has raced in both. From reviewers on YouTube, most said they would stick with the latter over the former if forced to choose.

In my opinion, the Next% is way ahead of the Streakfly for 5k. I was only about 7s off my 5k PB in the SFs, but my perceived effort was much higher and I had a lot of pain in the metatarsal part of my foot afterwards. Going to use it for track reps under 1k going forward.

I would take the Alphas for 10k+, just because they completely protect your legs - but I wouldn't say they have a great advantage over the Next% at this distance.

Does this shoe qualify as a "super shoe?" Does it come with the huge performance boost or is it more akin to a standard racing/training flat?

This is very anecdotal, but I ran a 5k time trial 4 weeks ago in VF and did a hard 3 mile tempo 2 weeks later in SF. The VFs felt much better. I think with the SF, they feel great at the start of a run and then start to get progressively harder to keep pace, whereas with the VF I could keep pace, but was limited by my speed.

Again, hard to compare a tempo with a time trial but here were the stats:

197 cadence with SF, 166 BPM, 7:10 pace, vertical oscillation / “bounce” 5.6cm, stride length 1.14m

196 cadence with VF, 169 BPM, 6:31 pace, vertical oscillation / “bounce” 6.2cm, stride length 1.23m

Maybe I’ll take the SF out for a true TT but I wouldn’t choose to, only to get a better comparison

I ran the Streakflys for a 5K and they were phenomenal. I think for a 10K I would def still race in the Alphafly tho.

I def think it should be considered a SuperShoe - its far better than the previous non-carbon plated versions and it uses the same foam composite as other Nike shoes. A shoe doesn't need to have 1in+ of stack height to be considered a SuperShoe, when I ran my 5k I was amazed at the speed and cadence I had they were amazing!

What about the Streakfly over the Dragonfly for a 5000m? I have both and I recently did a workout in them & the 1k repeats felt really smooth. However, spikes always feel a lot better. Anyone have any experiences?

Dragonflys 100% - Dragonflys are my fav spike all time, and the streakfly to me feels like it does its best work on the roads, on a track I feel most comfy in spikes.

The Labrat guy did a RE test comparing the Streakfly, Alphafly, and Invincible. He found the Streakfly were WORSE than the Invincible. You might like them, find them comfortable, etc, but they are a lot worse than the Alphafly even for 5k

I’m not trying to bash that guys study, because I love the content. However, that is a sample of 1 person and he’s a pretty big responder to the alphafly compared to the vaporfly. It wouldn’t shock me if he’s not a big responder to the stripped down streakfly. Also his control was the ASICS hyper speed, not the infinity.
