I'm torn between the 1400 and the Adios Boost 2 for my upcoming marathon. I did a 20 miler in the Adios and they felt fine. Longest run in the 1400's was 17 with no issues.
Anybody have experience running a marathons in both? Pros and cons of each? I like that the Adios is a bit more stable than the 1400s, but the 1400s are much lighter.
