Hey all -- Looking for some guidance on my next pair of supershoes for the marathon. I ran 2:38 this spring with a pair of Vaporfly 2s, and I'm looking to hopefully break 2:30 this fall/spring. I have ~100 miles on the VPs so am in the market for a new pair of shoes.
My dilemma: Should I go with Alphaflys or Vaporflys? On the one hand the VPs have served me very well, but on the other I've read a lot of review suggesting the Alphaflys could be better for the marathon. Also, I definitely heel strike -- how should that factor into my decisions?
Appreciate the input!
