Enough to Matter: 4%
A timely World lesson from Super Shoes
When Nike released the Zoom Vaporfly 4%, it changed running.
It didn’t make anyone superhuman or replace training. In fact, an outside observer might not even know the difference.
But it offered a stated 4% improvement in running economy.
That’s it. Four percent. That seems tiny right?
But people lined up to pay hundreds of dollars for that marginal gain. Pros from other brands were covering up the logo so that they could race in it.
Why? Because 4% is HUGE. It can be the difference between qualifying for Boston or the Olympic Trials and missing the standard. It could be the difference between a win and fourth place. Even those just looking to improve their PRs chose this shoe. All for 4%.
No one said, “Well, this doesn’t fix everything, so why bother?”
In endurance sports, we realize that progress doesn’t come from perfection. It comes from accumulation (of 4% margins)
Marginal Gains in Endurance Sports
We obsess over small improvements.
A slightly lighter shoe
A few grams off a gear kit
Maximizing fueling
Heat training
A little more sleep
I have cut tags off clothing for FKTs, and removed the insoles from shoes for races. In one interview, the host asked if I had broken my toothbruth in half to save weight… I had! Just for that marginal gain. No single change transforms you into something dramatically different. But stacked together over time, they absolutely do.
We celebrate this mindset in endurance. We write articles about it. We allocated millions to developing products with incremental gains. We praise athletes who spend years chasing tiny improvements.
And then we step into the world outside running and suddenly expect total solutions or nothing at all.
All or Nothing Doesn’t Work
I think one of the biggest mistakes we make right now is framing every problem as all-or-nothing.
If we can’t fix an issue completely, we treat partial progress as failure and eventually give up and move to the next issue. If a solution doesn’t address every angle, it gets dismissed, and when no solution is found, adopted, or fought for, we give up. It is disappointing to see the motivation, push, mobilization, and passion slowly fade away across so many issues.
That mindset doesn’t seem to move us forward. It seems to paralyze us. A window of passion and intense caring and adoption of the necessity of change, but then it fades away, and we move on with little change.
The entire world can’t be solved. It is just like ourselves, a work in progress. Micro improvements compounded over time. The world needs to be nudged forward.
And maybe it is just four percent at a time.
Outrage & Progress
Outrage is loud and dramatic. It feels powerful. But it rarely compounds. Outrage is exhausting. It is like going out too hard at the start of the race and realizing before the finish line that there is nothing left.
Real change looks boring by comparison. It is just like 4% super shoes. At mile 1, you may only be a couple of seconds ahead of your previous best. But it compounds.
A few small percentage positive improvements could be:
A community group that gets a little stronger. And has more cohesion, understanding, and impact.
A local policy change that reduces harm or increases safety to any degree.
A local organization that helps a few more people than last year
A conversation that doesn’t go viral but actually changes a mind
The problem is that none of these make headlines because such a large percentage of headlines are actively negative. Negativity sells papers (or gets clicks in the modern age). So when we don’t notice the small improvements we are making, we abandon our efforts. There is no finish line. It is a lot of 4% improvements stacked on top of each other. And that is so hard for our minds to comprehend. We are aimed at a goal we can never achieve, but continual forward progress should be the real goal, just like a thru-hike or an ultramarathon.
Stacked together, over time, these improvements matter far more than the loudest post of any singular day.
Avoiding Backwards
Here’s the part that matters most to me.
If we aren’t willing to accept incremental progress, we don’t stay neutral. We move backward.
In running, if you skip training because your fitness isn’t improving fast enough, you don’t stay the same. You get worse.
In communities, it’s the same.
When progress is mocked as insignificant, when unrecognized effort is treated as failure, when people are discouraged from trying unless they make a massive impact, the result is regression.
We’ve seen that play out. One hour a week (or less) in your community really can make an impact. Whether it is volunteering, picking up trash, maintaining a trail, or sending out the weekly email for a local non-profit. You have to trust that it matters. You have to find purpose in the process, just like training.
What If We Treated the World Like Training?
What if we approached big problems the way endurance athletes approach long goals?
Not with the expectation of mastery, but with continual improvement. Practicing consistency over intensity and effort over optics.
What if more people focused on improving one thing they actually touch instead of arguing about everything they don’t control?
That’s how records get broken in the endurance space and I think that is how communities get stronger. Momentum builds over time. That is how math works.
Four Percent Is Enough to Matter
No one bought the Vaporfly expecting it to carry them across the finish line by itself. They still had to train. They still had to suffer. They still had to show up.
The shoe didn’t replace the work, but it amplified it. And it also led to dramatic innovations and change across other brands. The shoe had an impact beyond its 4%, and we can too.
We don’t need saviors or perfect solutions.
What we need are millions of small, imperfect improvements, made by people willing to show up consistently.
We don’t need to be the loudest, expect instant results, or even try to measure our impact. We just need to trust that a couple of percentage points compounded over time with consistency will make an impact.



Thank you for this. So many things have given me chills within the last week - this is one of them.
Fantastic Jeff😊 thankyou I will share your post with my very thoughtful son
