Season 1 Official Ball - Faster and Safer
Size matters.
That's why we changed it.
Female football players tear their ACLs up to six times more often than male players. Head injuries are rising.
Still, the game is played with a ball designed for men.

“I saw too many girls get injured. And I couldn't ignore it.”
“As a football coach, I watched talented players drop out because of injuries. Knee injuries. Concussions. Girls who loved the game but couldn't stay in it. I had my own injuries. I know what it costs. At some point, it stopped making sense to keep doing the same thing.
So we started testing the one thing no one questioned. The ball. What happens if you change it? That's where our journey for a safer and better game started.”
Majken Gilmartin, Co-founder, UEFA B2 Coach
The Comparison
Every Other Sport Already Knew
Basketball, handball, athletics - most sports adjusted equipment for women decades ago. Football is one of the few where this remains unaddressed.
| Sport | Women | Men |
|---|---|---|
| Basketball | 325-375g | 567-650g |
| Handball | 325-375g | 425-475g |
| Athletics (Javelin) | 600g | 800g |
| Athletics (Hammer) | 4 kg | 7.26 kg |
| Athletics (Hurdles) | 84 cm | 106.7 cm |
| FootballUnchanged | Size 5 (same) | Size 5 |
The Reality
An ACL tear means surgery and up to twelve months of rehabilitation.
A concussion at sixteen can mean disrupted education and long-term effects.
This has real consequences for players.
The standard size 5 ball was defined decades ago based on male averages. Research now shows that equipment should reflect female biomechanics.
injuries per 1,000 hours of adolescent female football - one of the highest in any sport
players missed the 2023 Women's World Cup due to ACL injuries alone
ACL injuries in the current WSL season - at least one every week
Built to Change the Game
Sensational Ball 4.5
Designed for female players. Slightly smaller. Lighter. Moves faster through the air. Requires less force with every touch.
Size 4.5, 370 grams. Developed with researchers at the University of Copenhagen and Aarhus University. The first gender-specific football ever created.
Faster
longer passes
faster ball speed
Higher tempo, less effort
Safer
head acceleration reduced, below concussion threshold
lower biomechanical strain on knees and body
Less time at maximum heart rate
Proven in Play
of players responded positively
said the game felt more fun
What It Means on the Pitch
Players stay in the game longer. And play it better.
The Evidence
The Science Is Not New
In 2024, the International Olympic Committee published the FAIR Consensus Statement - 109 researchers, over 600 studies, more than 600,000 participants - concluding that sports equipment should be gender-specific, and that ball size and weight should reflect female biomechanics.
A 2025 BMJ study on English professional football found that concussion accounts for 7% of all injuries in women's international football - compared to 2% in men's. The same sport. The same ball. Dramatically different outcomes.
What is new is that it is now impossible to claim we did not know.
“When the ball is hit well, you can pass it further and more precise - both in the air and on the ground. The dribbling is faster and safer, especially when changing direction.”
Tina Theune
Former Germany National Team Coach. Six-time UEFA Women's Championship winner. FIFA Women's World Cup winner.
“Among female soccer players who had sustained ACL injuries, more than half developed x-ray signs of osteoarthritis in the following 12 years.”

18 Years in the Making
It Started in 2008
This is not a story about what is wrong with football. It is about what it could be.
2008
The Question Nobody Asked
Majken Gilmartin, coaching U15 girls, watches her players struggle with headers and carry strain in their knees. She refuses to accept it as normal and begins testing a modified ball with researchers at the University of Copenhagen and Aarhus University.
2011
FIFA Says No
The research is shared with FIFA. The response: the market was not yet ready. Not that the data was wrong. The market. Majken stops waiting for permission.
2011-15
Balls With a Cause
A series of ball designs tied to real causes: raising funds for refugee women in Denmark and Afghanistan, celebrating women’s right to vote with former Danish PM Helle Thorning-Schmidt, and supporting the first women’s refugee football league with Red Cross.
2015
The United Nations
In partnership with UNDP, the official UN Sustainable Development Goals ball is created - displaying all 17 Global Goals. The ball becomes a symbol far beyond football.
2016
Denmark’s Largest Youth Study
“Pigernes Stemme” (Girls’ Voices) - the biggest research project on youth girl football in Denmark, created with Copenhagen University, TrygFonden, and the Danish Football Association.
2024
The World Catches Up
The International Olympic Committee publishes the FAIR Consensus Statement - 109 researchers, over 600 studies, more than 600,000 participants - concluding that equipment should be gender-specific. Ball size and weight should reflect female biomechanics.
2026
The Sensational League
After 18 years, the ball is no longer a research project. It is the centrepiece of a professional league built from scratch for women - where every decision is made with female players and fans at the centre.
She stopped waiting for permission and started playing.
“We cannot let girls and women knowingly play with a ball that gives them life-changing injuries. That sentence should not be controversial.”
“And yet here we are.”
