The longer races is where this spike really shines, 3k-10k. I personally have used it for 3k-5k but not 10k (though I know many people who have and can attest this spike is great for it).
For shorter races such as 400m-1600m, the spike was fast enough to still perform really great. It may be too soft for others to enjoy at those distances but I personally really liked it.
Bouncy and fast ride
It's extremely bouncy and supportive enough to get you through races without your legs or feet feeling beat up.
The plate is a full-length stiff Pebax plate that contributes to a smooth, and efficient ride. It had a great blend of snappiness (not as much as a carbon fiber plate) and toe-off while also keeping a smooth transition.
The midsole of this spike consists of Nike’s premium ZoomX foam. ZoomX is Nike’s lightest and most responsive foam. It is made to be soft and light, which is why there's a good amount of foam in this spike, while still staying lightweight.
I found it to be exactly that while racing, which is why it's comfortable enough for distances 1500-10k. I also love the high amount of arch support which is good for keeping the feet feeling fresh during the longer 3k or 10k races.
Premium spike plate
The outsole of this spike consists of a full-length spike plate, sharkskin heel for extra traction, and outsole foam for some extra durability.
This spike utilizes 6 removable stainless-steel pins to grip the track and ensure no slipping.
In terms of flexibility, this spike has very little flexibility which is what makes it so fast and versatile.
Nike Dragonfly is super breathable
The upper of this spike is Nike’s Fly Mesh upper, which was updated with extra perforations for extra breathability.
It also utilizes a Matumbo hole in the heel which cuts down the weight and adds comfort.
Tongue doesn't fit properly
The only problem I have with the upper is that the tongue bunches up when tying the laces down.
A small detail I really enjoyed is the notched laces which ensure they don’t become undone during the race.
Sleek and comfortable
In terms of looks, I really enjoy the look of this spike. It looks fast, sleek, and very comfortable, which it is.
Costly at $150, but worth it
The price of this spike is $150, which I feel is justified by the amazing quality you get in this spike.
Nonetheless, it's still one of the more expensive spikes on the market. That being said, you get a versatile spike that can produce extremely fast times in the 1500m-10k (even 800m which I have raced it in).
I race distances between 800 meters and 10K whether it be on the track, the roads, or on cross country courses. My typical training consists of easy days, long days, workouts (fartleks, tempos, interval training, etc.). My typical training paces range from 7’30 a mile on easy days to sub-5 minutes a mile on fast interval days, and with many paces in between. I run anywhere from 40-60 miles a week. My personal bests are 2:00 for 800m, 4:30 for 1600m, 9:50 for 3200m, 15:57 for 5K, and 34:10 for 10K.
