I am deciding between zoom fly 4, tempo next % (I found a deal for 160$ un-used), or streakflys. what would be best for tempos (up to 5 miles, high 5 min pace) and intervals (800m+) and possibly some indoor track miles/3200s on a concrete indoor track.
I don’t know what your best option is, but I’ll say that I like tempo next % much better for dirt and crushed limestone trails than for asphalt and concrete. I wear them for any long runs with quality miles and for workouts (pace range has been 6:00-7:15) on those surfaces, and I like them (not outstanding life in them, by my experience with three pairs has been better than for some reviewers). On harder surfaces and tracks, I’ve used Saucony Endorphin Speed and Pro for threshold and tempo work (just fwiw, even though you’re not considering those).
I'll check them out
ASICS magic speed 3 is also a great option.
rebel v3
endo speed 1/2/3
zoom fly 3-4
magic speed 2-3
deviate nitro, any
used vaporflys/alphaflys
endo pro 2
Indoor concrete track is wild
IMO the streakflies feel the best for intervals and Vaporflies feel the best for tempos. Vaporflies have much better durability though. But out of the shoes you mentioned, probably the streakflies.
