We can create a better world through sport

Soccer is one of the world’s most powerful communication tools. We reshape the landscape of sports through soccer – always guided by our promise.

Eir’s promise is to embrace all safety, competitive, and playful aspects of soccer. We are committed to raising awareness of gender equality and access to all in soccer, which has lead us to:

Use soccer and the ball as a means of creating a better world where poverty or other unsustainable conditions exist.

Stand up against the severe injuries as well as gender stereotype in soccer – and support women to live a full life with soccer.

Our brand ‘EIR’ is inspired by Nordic mythology: Eir is a goddess and valkyrie associated with medical skill and a healing goddess.

Faster play. Longer stay.

Today young girls and women are playing soccer with a men’s size soccer ball. Most other sports like basketball, golf, tennis, and hurdle race have adjusted equipment to give players the best chance to succeed. In soccer, players aged 14-19 suffer one serious injury per year. With a 90% chance of a suffering second injury, many of them retire from the game before they ever reach their prime. The Eir balls have been developed to fit women’s size and weight, to reduce injuries and enable a faster game.

Today, we know that there are 6x as many injuries in women’s soccer as in men’s and that women suffer more head injuries in soccer than men do in ice hockey.

The Eir ball is the product of three years of research by scientists in Denmark and Germany supported by the German and Danish football/soccer associations. The Danish Football Association has granted permission to play with the ball for all age groups except for the pro adult league.

This is still a BIG secret … 🙂

Events for a good cause

Inclusive model 2
Our inclusive model guides our events in general. In some projects, however, we pay particular attention to important issues such as the UN Global Goals, gender equality, and other sustainability issues. These projects are organized in close cooperation with partners such as:

Logo ministry of foreign affairs of denmark

By offering both safe, competitive, and playful ways of playing soccer we increase the ability, confidence, and desire to be active.

Inclusion is not just a philosophy. It’s a commitment to new traditions.

Music festival events

For the last five years we have gathered thousands of soccer playing girls, a large crowd of spectators for a three day street soccer event – at the 100,000+ people Roskilde Music Festival.

To us, creating events at music festivals is brilliantly fun.

Urban Events

Sports event developed and facilitated for the City of Copenhagen and the International Olympic Committee.

ver the years we have created +50 city tournaments together with fashion stores, media companies, gowernmental bodies and charity organizations.

There is no doubt that it’s beneficial for the City of Copenhagen to support Eir Org. It’s brilliant city branding. As a city, we want to be known for hosting such events. Eir Org is fun, creates friendships and networks and inspires us to be active and creative. I have worked with the people behind this sensational event in regards to the Climate Summit for Mayors, that I hosted last December and they have a strong flair in making people feel that they are connected and doing something that matters.

Camps are a great chance to both learn and have fun. With our camps we set up an environment for fun and teaching soccer skills as well as a broader understanding of the game. We equip girls with a soccer intelligence that enables them to make the best decisions on and of the field. We always play with Eir Soccer balls that match their maturity and enables them to play safer and faster. This gives the players new ways of using their technical skills both individually and as part of a team. We organize camps lasting two hours to three days subject to age groups:

4-7 years (Angel Dust Camps)
 7-9 years
10-14 years.

The camp concepts have been developed in cooperation with former professional players such as Becca Todd – national beach soccer team player; Futbolistas Coaching Director, and sports scientist who has volunteered making kids smile all over the world – and Bettina Falk – former Danish national team player with 86 caps; FIFA end UEFA licensed soccer coach.

Soccer Fitness

Nytårscup 2014
occer fitness programs aim at anyone who wants to learn or refresh skills, have fun and get a brilliant workout. College students, moms, players or non-players at all ages will benefit.

We conduct pop-up, indoor and outdoor soccer fitness classes running 2-12 weeks. Talk to us about great activities at your school, college or company.

Soccer fitness may also be planned in addition to the soccer camps for the young girls as a 2 hour training for parents while their girls are at camp.

Physical literacy and health

From a health-perspective, soccer has important benefits, such as reduced risk of obesity and diabetes, but also includes an inherent risk of injury. Since 2008 we have conducted research of injuries and ball behaviour together with scientists in Europe.
Using share of voice as a measure of the public opinion on sports injuries and sports health – the concern has reached a level that has launched a hunt for answers to concussions, ACL tears and better ways of playing sport among health professionals, players, parents and other stakeholders.


Key facts

Most other sports – e.g. basketball, hedge and golf – have adjusted the game/and equipment to women to give the performer the best chance to succeed. Football/soccer stands out as one of the few sports where gender equality adjustment remains.

The average female soccer player aged 14-19 suffers one injury per year.

There are up to 6x as many injuries in women’s soccer as in men’s.

Women suffer more head injuries in soccer than men do in ice hockey with the number of head injuries second only to men’s football/soccer.

With a 90% chance of a suffering second injury, many players retire from the game before they ever reach their prime.

When women kick a standard size 5 ball they lift the leg too high. This makes it difficult to create speed and puts stress on the knee alone instead of spreading stress over both knee and hip.

Women’s head acceleration when heading a standard size 5 ball is above the level where concussions can occur.

If a specific player is able to kick a standard size 5 ball 33 meters, then the same player can kick the Eir ball 37.4 meters (13% longer).

A 20-meter pass (not touching the ground) will take 0.91 seconds with a standard size 5 ball and 0.85 seconds (6% less) with an Eir ball.

Ball speed is higher when kicking the Eir ball vis-à-vis a standard size 5 ball (23.9 m/s vs. 22.5 m/s) – given no difference in the foot speed.

50% of the players find the Eir ball better than the standard size 5 ball and 86% of all respondents respond positively to the Eir ball.

In long passes the Eir ball moves particularly better.

Nearly half of all respondents stress that when playing with the Eir ball, they have a better feeling than with the standard size 5 ball.

66% of the players think it is more fun to play with the Eir ball.


Research: Injury-incidence, heart rates and concussions


Research: Biomechanics of kicking – male vs. female kicking

The increase in level of sports injuries, particularly tears to the anterior cruciate ligament (ACL) of the knee, increases risk of osteoarthritis, even if it is surgically repaired.


Among female soccer players who had sustained acl injuries, more than half developed x-ray signs of osteoarthritis in the following 12 years.
Marci A. Goolsby, MD, Attending Physician, Dept. of Medicine (Sports Medicine), Hospital for Special Surgery


Injury-incidence in adolescent female soccer is 15.3 per 1.000 hours of soccer-exposure. This is extremely high.

The level of wear & tear injuries is high. Strain of legs are higher  with a standard ball 5 than with the Eir ball (5.2 vs. 3.7).

Too long time is spent at high heart rates. Players unaccustomed to the Eir ball spent more relative time over 95% of HRmax and less relative time in 80-90% of HRmax, when playing with a standard ball 5.

Head acceleration will be significantly lower – even at an increased ball speed – when using the Eir ball with lower mass vis-a-vis the standard ball 5.

Female kickers tend to move both the thigh and the shank towards the ball, whereas the male kickers only rotate their shank. Changing the movement with the Eir ball can remove pressure on the female knee close to zero.

Testing of the ball at Oure Sports and Performance school:

With the new women’s football/soccer ball, elite women kick the ball with 4% higher ball velocity.

Elite male football/soccer players achieve maximal ball speeds of approximately 30 m/s when kicking under laboratory conditions. Female players, however, only achieve speeds of up to 22 m/s.


When the eir 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.

If a player is able to kick a standard size 5 ball 33 meters, then the same player can kick the Eir ball 37.4 meters (13% longer).

A 20-meter pass (not touching the ground) will take 0.91 seconds with a standard size 5 ball and 0.85 seconds (6% less) with an Eir ball.

Research: Ability, confidence and desire

Fifty (50)% of the players find the Eir ball better vis-a-vis a standard 5 ball.

86% of all respondents respond positively to the Eir ball.

Nearly half of all respondents stress that when playing with the Eir ball they have a better feeling.

66% think it is more fun to play with the Eir ball.

60% want to continue to play with the Eir ball

53% say that playing with the Eir ball is a special experience.
