Nike Vaporfly/Zoom Fly sizing

From a review on Running Warehouse...

Comments: I was lucky enough to snag a pair of these when one my size (10.5) became available last week. I'm 5'11", 140 lbs, 3:30 marathon.

I have an incredibly narrow foot, especially in the heel. An 11 in Zoom Streak 6 fits me perfectly. The 10.5 Vaporfly fits well when cinched down. I wish the heel were more snug but there was no slippage. Took them out for a 10 mi tempo this morning (my usual tempo shoe is the zoom streak or adios boost 3). They were amazing. I was on minimal sleep with a tight lumbar section this morning. I took it easy first couple of miles but once settled in, was able to comfortably run 7:30ish, where as I am usually closer to 7:50. I felt far less beat up at the end of the run. I believe the hype. I'll be wearing these for Chicago in October.

I am a consistent 12 in New Balance and Nike Pegasus. 12 is just a shade tight on me in the Zooms, Vapors and Zoom SPs. I've run a lot in a pair of 12.5 SPs and been very comfortable but I've also done 65 race miles in 2 pairs of size 12 Vapors without any real rubbing or issues so it's a very minor thing.

Great. Thanks to both of you!

I wear 9.5 in vomeros and 9.5 in Vaporfly 4%s

Yes, correct. They run half a size smaller than zoom Fly.

I wear 10 in Pegasus, 10.5 in Zoom Fly, 10 in Vaporfly fits perfect.

I have put my size 11 vaporflys next to my size 11.5 zoom flys. The size 11 vaporflys are longer than the 11.5 zoom flys.

Wish I saw this thread before. I got the Zoom Fly size 11.5. Really tight, have to wear think socks. Vapor Fly 11.5 fits perfectly.

Why TF do they do this?

One more data point:

The zoom fly 12s fit perfect on me.

Just got the vapor fly 4% in the mail and the 12s seem a bit too big, the 11.5 would have been perfect...

...but I doubt a find a pair in time for Houston.....crap.

I just received a pair of size 10.5 Vaporfly 4%. I have a narrow foot and wear size 11 in adidas Boston Boost, but 10.5 in most everything else, including Brooks Racer ST, New Balance Zante, Nike Pegasus.

The 10.5 Vaporfly fit a bit wide and I had to cinch down the laces, but seem to be the correct length. I'll follow up once I've run in them a few times.

Any word on how they fit/feel?

I'm curious about the fit of this shoe.

I typically train in a lunar glide 10.5, but race in lunar racer 11.

I train in the Lunarglide size 11 and wear the Vaporfly in 10.5.

I’m a 12.5 in the Zoom Fly and a 12 in the Vaporfly.

FWIW, I train in Lunarglide 10.5.

I bought vaporfly 4% in both 10.5 and 10.

I preferred the 10.5

Raced a marathon in it last weekend and it was perfect. It took one 12 mile run the week before to get used to it, but I'm sold.

I am a perfect 12 in the Zoom Fly. Based on this info I ordered an 11.5 in 4% last week. They came in the mail today and fit perfectly, so thanks very much for the data point.

It’s weird that Nike does this though, it really can’t be that hard to have consistent sizing for the same line of running shoes. They have to know that the 4% runs a half size larger than the zoom fly.

I bought mine in the same size as the Pegasus per the recommendation of the Nike website (10.5) and they fit perfect. Maybe .5cm of extra room in the toe or exactly as my Pegasus fit.
