Just for the OP or anyone else who's wondering why we're all harping on the Endorphin Speed in particular as opposed to other racing shoes is that it shares the same foam as the Nike's, has a nylon plate for rebound.......
The Saucony and Nike shoes do not use the same foam.
Nike uses Pebax foam. On a side note so does Mizuno and they been using it longer, just a different density/rebound/springiness. Not all Pebax runs the same.
Saucony uses a TPU foam that is close to Adidas's Boost foam. Why is this significant?
Boost is The Foam that started the shoe foam craze. IMO it's the biggest foam breakthrough of this century for running shoes. It's the foam that was first shown to increase running economy and at one point something like 12 of 13 world records set in the marathon were in Adidas shoes. It's the foam that sent Nike and everyone else back to the drawing board.
All these shoes are going to give people 1-7% increase in running economy. You could try them on and shoe A could be 2%, Shoe B 6%, Shoe C 5%. For someone else they could get shoe A at 6%, B at 1% C and 3%.
I'd not pay too much attention to which shoe is the fastest on elite runners as you and I don't run like them. In fact Asics is launching shoes that are tuned for running velocities.
Try on a bunch of these shoes and get the one that feels the best. For instance I thought the Next % felt the best underfoot when trying them on. I ran .25 mile in them and thought they ran like dogshit. Ended up with Endorphin Pros. \_O_/ Each his own.
You are correct that the Saucony Speed has a nylon plate the Pro has a carbon plate.
