Endorphin Speed vs Pro (Tempo and long runs)

I have the speeds and love them. They’re getting up in mileage and want to buy another pair of V1 as they’re starting to get discounted for the V2 launch.

Current easy day shoe is the Invincible Run.

Speeds were an everyday show are now used mostly just for tempo/fartlek/“track” repeats.

Switching between Invincible and Speed for Saturday long runs depending on if I’m going easy or faster.

So question is, after a year, anyone have a strong preference between the speeds and pros for the above mentioned workouts?

I’m curious if the carbon plate would be any benefit for this type of work, which is fine usually at 6:35-7:45mm. I’m 6’0”, 165lbs, and HM pace is 7:30. Just as reference since zoom flys have always been unresponsive and sucked for me. Could never get fast enough to utilize the plate in them.

Seems like a handful of people comment that the pro is really stiff compared to the speed.

Still COVID restrictions in running stores, so can’t use treadmills in stores and I’d rather not buy from runningwarehouse, use a couple of times and return a used pair of shoes to them, you know?

K. Thanks for any additional insight.

There was a research study done with a pair of Vaporfly 4% Flyknits. Researchers tested running economy on some test subjects, then cut the shoe through the forefoot of the plate in 6 places so the forefoot of the shoe bent like a Nike free. Then they reran the running economy test. Gait parameters changed but running economy was unaffected by the modification. Stiffness provides a sliiiiiiight advantage, until it doesn’t, and that’s subject specific. That’s why carbon fiber never really caught on for a long time until the Vaporfly.

So what’s the difference between the two? About $70.
