Zoom Fly Sizing

I have all 3 shoes, size 12-1/2 across the board. The Adios is the tightest fitting of the bunch.

I know that people generally say that the zoom fly is a little tighter than the vapor fly. I find the vapor fly to be a really comfortable 12.5. However, the adios are a hair tight in a 13.

I wear a 13 in Hoka, Solomon and Nike(lunar glide) but for the ZoomFly and Steak 6 had to go up to a 14

The vaporfly and zoom fly are completely different shoes. The vaporfly run 1/2 size big, or even a full size big.

I have been a 9 in Nike for several decades. Zoom Fly is the first one I needed in 9.5. And, sadly, they are not working for me. Trying to sell off four pairs in diff. colors.

I'd second this. I'm a 10 in Adios Boost 3 and went 10 in Zoom Fly. Both are fine but Adios is a bit tighter in the toe box.

Interesting that you are getting different answers

My 11.5 Zoom Fly is tighter ( but still fits) than my 11.5 Adios 3. My 11 Vaporfly fits similar to my 11.5 Adios and a little looser than my 11.5 Zoom Fly

OP here. Interesting. So if you were to run a hilly course (Boston) you'd go a half size up to a 12 in Zoom Fly or stick to the 11.5?

I personally would always pick the tighter option for a race- I cannot stand any extra room- I love the fit of my tight Zoom Flys- so 11.5 for sure-12.0 if using as comfortable every day trainers . Not sure anyone uses Zoom Flys as everyday trainers though

Ended up going 10.5 in the Zoom Flys, same as Adios, Boston Boost, and Brooks Launch. Zoom Flys actually fit the loosest of the bunch, but are fine - toe box seems a little wider.

As for the ride, the jury is definitely still out. The Zoom Flys are insanely stiff - my feet and legs are beat up running in them so far. Maybe this is by design with the nylon plate in there and the increased energy return (which I'm not yet really feeling)? Maybe they'll break in over the next week or so? Was thinking of running Boston in them but I may stick with the Adios or Bostons..

I would have tried on the Zoom Flys at one of my local running stores just for fun, but they only had the women's version in stock. Anyway, I picked up the display shoe and tried to bend it--stiff as socced cleats. Ended up buying the Streaks.
