Just had a look at these. Honestly, pretty impressed at what I see here (other than the colors, haha) - Rebecca Broe and the team have done a great job.
First thing I notice is the last shape - very Nike footscape-esque which is a good thing. Upper is nicely done, nice clean engineered mesh with a little bit of interest with that eyestay pattern reading "flexibility".
Obviously though everything of performance value in track spikes sits in the midsole/plate. The MD is really well done with the little midfoot window there which definitely adds some intuitive attraction there with respect to a spring (even though it's not), but the overall silhouette is nice - especially in the heel. I would guess that that little "carbon fiber" piece you see is just a midfoot shank to stop that window collapsing and it won't go into the forefoot because of WA rules which say you can't have two plates on top of each other and there is no room for it anyway.
LD is a little different but again nicely done - your carbon fiber piece there I would guess just splits out and runs under the spike receptacles because really there is no need for it to be a full plate under the entire forefoot - it would be way too rigid for a distance spike anyways. They had to save a few $$$ by going with a pebax spike plate (because it's a bit soft and dense) but it's pretty stock standard in the industry.
I don't know what foam they have but by now almost all companies have access to some kind of pebax/TPE based foam which is about the same in terms of weight, compression set and resiliency. I'm sure no different on these spikes.
As for number of pins etc - want to know the truth? Don't even need them - yes, even in the wet. Between the friction of the track surface and any secondary element (molded) grip on the plate there is more than enough traction. They just add unnecessary weight. Why have them then - convention and perception - almost impossible impossible to sell a track "spike" that doesn't have "spikes". Maybe one day.
Overall I think these look really nice. They look clean and fast, have some unique details and I would doubt the performance of these let erode any of those attributes. Good to see another brand investing in track running product (because many don't as they make no money for brands) - it will help raise the investment and level of product across the board.
