How many races can you get out of Vaporflys?

You are going to use them on the track?

I think they still feel pretty good after 100 miles on the road but not sure how the track surface would affect them.

They are good through around 100 miles, then the foam starts to break down a bit and might lose a slight bit of speed.

But don't use them on the track if that's what you're planning, regular track spikes will make you run faster on the track. You can't wear spikes on the road, thus the vaporfly becomes the best option for roads.

Don't use vaporflys on the track. Just wear track spikes.

BYU dominated on the tack last year wearing them.

I raced in the original 4%s for about 100 miles. They were still fast but I got a good deal on a pair of nexties. I’ve raced about 75 miles in the nexties, mostly on the roads but also on the track. They feel good as new.

I still wear the originals for track workouts and longer road tempos. They probably have 400-500 miles on them. They are pretty squishy in the heel but they still feel fast.

So to answer your question, I think you can get at least a couple years out of them if you’re just racing shorter distances. You’ll probably need a new pair before your senior year.

Exactly. I'd race in them 200-250 miles, then use for another 200-250 in workouts.

I wore Mayflys for 6-800 for a few years.

Considering Nike now has a 4% spike.... why not use that or am I missing something?

Nike Viperfly or whatever its called.

When will you idiots realize that the VF IS faster on the track? Louie Serafini ran 13:47 over the weekend on an indoor 200m banked track with them. They ARE more efficient than anything else. Yes, even including your precious spikes. Perhaps on a web surface spikes will help, but on a dry surface, track or road, you're at least 4 percent more efficient. Why wouldn't someone race in them for 5-10k and longer is beyond me. As others pointed out, BYU wore them last outdoor ncaa. Expect 98% or more of runners in the finals this year to be wearing them.

Id happily race 3000m & up on VF unless the track was wet.

That is a spike for 100m

You don't need Vaporflys for the track. Tracks are already designed for energy return. Vaporflys are designed for energy return for road use. Roads are not designed for running -- no energy return there.

Vaporfly's don't return energy and neither do tracks. They do however make you more efficient, which leads to you racing faster. Tracks don't do that. Again, you will run faster with VFs on your feet than any other footwear in existence, regardless of surface. This is a proven fact. Tests were done on a treadmill and all evidence points to them leading to faster times. Only a fool wouldn't wear them for any race that is 5 or 10k regardless of surface.

Do you have scientific evidence to back up that claim?

Go for it. Anyone telling you that VFs aren't worth the same on a track as they are on the roads have not recently been to any legitimate collegiate distant event. From slow heat 3ks to balls to the wall 5ks, VFs are being worn. I'll stick with my spikes for steeple and if I run anything below 5k, but I'll acknowledge that my not wearing them for indoor 3/5k and outdoor 5/10 puts me at a competitive disadvantage

I'm a collegiate sophomore and I've been using the Vaporfly Next% for 3k's and 5k's this indoor season. They perform beautifully. While I see the appeal to sticking with spikes, I personally prefer the Vaporfly. I saw a slow-mo of me in the 3k, and (compared to spikes) my stride length in the Vaporfly was significantly longer than in spikes with no extra effort required. I was blown away.

Here's what I think you should do: save a pair of Next% exclusively for racing, and get a second pair to do your workouts in. There's a ton of evidence that racing and working out in the same shoe is great for your bio-mechanics on race day. I have one pair of the Next% that I've been doing workouts and races in, and I am beginning to worry that it won't hold up as long as I want it to.

Some of these posters are correct. The VF is better than a spike. The only reason pros still wear spikes is due to tradition I think. Nikes top guy in US run specialty believes the VF will eventually make spikes obsolete.

You're completely right. In all of the meets I've been to recently there have been several runners in each 3k and 5k wearing Vaporfly's. In my most recent 3k I counted three of us wearing the Next% and four people wearing the 4%. One guy wore them for the mile (he got last in his heat)

Zero percent of world championships or olympic qualifying times in the past year, and zero percent of NCAA indoor championships times this year have come with 4% or next % shoes. There is no rule saying they can't be worn on the track. So there's some pretty big evidence. If it was legal and they were faster than spikes, then people would be wearing them everywhere. But they're not. I know people who have run in them on the track and they didn't run very well.

Not everyone will respond the best to Next%s, so to say they are the fastest shoe is not true. I would think that on a 200m indoor track, spikes probably handle the turns better than the Next%.

As far as your claim that 98% of 10k finalist will be wearing them. First, I really don’t think it’ll be that high. Second, I would reckon that the same athletes would make the finals regardless of shoe worn.
