Loved the Hyperspeed 3/4 for distances up to the half marathon. The 5 is a different shoe. To me, seems less responsive and doesn't fit the same. I know the 6 is supposed to be out soon (Jan '14?) but that's an unknown and not out yet.
Anyone have luck finding comparable shoes to the Hyperspeed 4?
Just bought the NB 1400 v1 and that seems promising.
Have you looked at the Asics Pirhana?
NB 1400 are too thick and clunky. Step down to the NB 1600, which has about the same feel as the Hyperspeed.
If you liked the Hyperspeed, ignore the previous poster who suggested the Piranha, which may be too thin for your liking. It's a true racing flat to be used only in speedwork/races.
He likes the hyperspeed 4, which is much like the piranha, and not like the clunky hyperspeed 5. Of course, that's my opinion, and you're entitled to yours as well. It is more of a true racer, but is still closer in resemblance to the hyperspeed 4 than the 5. This all depends what you are using them for: strictly racing or as a racer/lightweight trainer.
Thanks for the replies.
I have a pair of the Piranha 3's and like them but have only used them on the track. Don't think I'm efficient enough to use them on the road.
The NB 1600 looks interesting. The specs on Running Warehouse do look similar to the hyperspeeds.
