The need for football footwear improvement:

According to "The Guardian":

"Steve Bruce (Sunderland's Manager) has called for a conference on footballers footwear and the state ofmodern pitches in the wake of horrific injuries suffered by players wearing fashionable blades rather thanconventionally studded boots. Already this season Manchester Uniteds Antonio Valencia and SunderlandsFraizer Campbell have sustained appalling injuries after their feet became trapped in the turf as they contestedpossession. [1]

The Sunderland manager said. I think weve really got to look at this because there is a problem. It would beinteresting to see some research into modern pitches and also footwear, which, on a lot of occasions, leave a lotto be desired. [2]

Antonio Valencia, for example, was wearing a pair of Adidas boots while gett ing his injury. Every Adidas boothas different stud configurations standard, which makes it hard to regulate. For example, youre likely to catchMessi wearing his Adidas F50 Adizero with a circular/hybrid stud configuration like this (Figure 1.0) :

These days there is no s tandard for comparing or class ifying the shoes in to appropriate stud/blade configuration. Thishinders legislation or restrictions to be implemented on the use of footwear. It is proving to be a death trap for footballers

from all levels of abilities . Former Liverpool player and current footwear designer Craig Johns ton said: "People say that the boots dont provide enough protection. In fact the oppos ite is true. The problem is that the boots areso well made there is no give at all in the materials especially the cheaper s ynthetics.[3]

Th e skin and superficial muscle:The skin and muscle starting from the ankle and covering the foot is made up of two layers.

The upper layer which is smooth, soft and has the capability of sliding on the underlying matrix of

bones and blood supply.

1.

The denser, stronger muscle group which provides the holding "gel" to keep the veins, arteries andlymphatic supplies an also the bones.

2.

Referring to injury prevention the following points are of particular interest:

The foot is particularly very well supplied with blood and lymph supply and drainage.

In a relatively less amount of muscle a large number of bones and vessels are found.

Figure 3.0 shows the main sheaths of muscles closest to the superficial skin layer which are most prone

to injury due to high impact (Ball or other players) in the case of insufficient shielding from the shoe.

Although the bones of the foot are solid in structure (as apposed to the "softer collar bone"). The foot

contains some of the thinnest and most vulnerable bones in the whole body. The most common foot

injury (discussed in introduction) is/are the broken metatarsal bone(s). These are the bones that lie half

way through the foot and join tarsus and phalanges (Other bones) see figure 4.0.

Fig 4.0

Muscle InjuryThe second most common injury of the foot due to inadequate footwear protection is the "sprained

ankle" . This is a muscle injury in which one of the ligaments get over stretched or torn (Figure 5.0)

The dreaded metatarsal curse has struck some of the Premiership's top footballers

in recent years.

Manchester United's Wayne Rooney fractured the base of his fourth metatarsal before his

miraculous recovery for the 2006 World Cup.

So what exactly are metatarsals, and how long do they take to heal?

WHAT?

Metatarsals are the five long bones in the forefoot which connect the ankle bones to those

of the toes.

The first is linked to the big toe and the fifth, on the outer foot, links to the litt le toe.

The five metatarsals act as a unit to help share the load of the body, and they moveposition to cope with uneven ground.

Injuries usually occur as a result of a direct blow onto the foot, a twist ing injury or over-use.WHO?

Rooney has broken his metatarsal two times but there are many players who have suffered.

Others include Steven Gerrard, David Beckham, Gary Neville, Roy Keane, Ashley Cole,Ledley King, David Nugent and Michael Owen.

But damage and recovery t ime depends on the extent of damage and which of the five

metatarsals is affected.

HOW?The middle metatarsals - which are the longest and narrowest - are usually injured as a

result of wear and tear (stress fractures).

Will Rooney be fit for the World Cup?

In other words, it is caused by an ongoing process - and not one single occurrence. This iscommon with athletes, ballet dancers and soldiers.

Impact (eg: someone stamping on your foot) and twisting can also result in fractures.

The first, second and fifth metatarsals are the most commonly injured in sport.

The first links to the big toe and is shorter and wider than the others. It is estimated this

bears up to one third of the body weight.SYMPTOMS

Pain in the bone during exercise, bruising, swelling and tenderness in the foot when weight -

bearing.TREATMENT

Rest. The immediate response is a big "no" to all exercise and sport for 4-8 weeks.

The patient may be asked to wear walking boots or st iff-soled shoes to protect the injury

while it heals.If the cause is over-use, then treatment can vary hugely. Training habits, equipment used

and athletic technique should all be investigated.

Guide to broken bones

With a bone fracture, the bone can often have a pin or screw inserted to speed up the

recovery.RECOVERY

It all depends on the damage and which metatarsal bone is involved. It is impossible to put

a timescale on recovery from a stress injury.

RECOVERY TIMES

Michael Owen (2006): Fifth metatarsal - predicted 6-8 weeks returned 17 weeks laterWayne Rooney (2004): Fifth metatarsal - predicted 8 weeks returned 14 weeks laterDavid Beckham (2002): Second metatarsal - predicted 6 weeks returned 7 weeks later

Gary Neville (2002): Fifth metatarsal - predicted 6-8 weeks returned 21 weeks laterAshley Cole (2005): Fifth metatarsal - predicted 6-8 weeks returned 12 weeks later

Scott Parker (2004): Second metatarsal - predicted 8 weeks returned 34 weeks laterDanny Murphy (2002): Second metatarsal - predicted 6 weeks returned 21 weeks later

Steven Gerrard (2004): Fifth metatarsal - predicted 6-8 weeks returned 10 weeks later

After initial rest, the training techniques or body mechanics may need minor tweaking or amajor haul to avoid a repeat injury.

With an impact fracture, after the plaster and protective boot is not needed (usually after

4-6 weeks), it will be a case of exercise and increasing weight-bearing activities.

Ice packs, strapping and even the use of oxygen tents can be used to assist recovery.

Full return to action can be anything from another four weeks and upwards - depending on

the extent of initial damage. Young bones heal quicker.

One factor that also helps is if the broken bone is one of the three inner metatarsals. As was

the case with Rooney.This means that the fourth metatarsal is aided by the 'splint effect' of the bones on either

side.

Preston's David Nugent broke his fifth metatarsal in March 2006 and returned to action after

being sidelined for just six weeks.

His remedy? Drink plenty of milk.WHY SO MANY INJURIES?

The breaking of a metatarsal seems to be increasingly common among England's top stars.

There are many theories being put forward to explain why so many players have fallen foul

over the last few years.

Some believe it is the number of games played at the top level, some say training is more

intensive, and others argue that training on artifical surfaces has a higher impact the body.

Evolving designs of boots have also come into question.

Many boots are now much lighter and more flexible, with a variety of new studs and bladesavailable.

Some suggest that players' feet are less protected and supported than a few years ago.

To conclude, most of the current footwear in the market lacks adequate protection and is focused only

on enhancing the performance (high grip, low weight) . This means that the due concern to comfort,

safety and protection is not given.

High profile recent injuries at crucial times ( Rooney injured before world cup) and higher frequency of

injuries due to problems like over grip are attracting professional attention. This is opening the market

for better footwear protection as general consumer from recreational players to professionals arehungry for better footwear.

One of the lines of thinking might be the development of a footwear protection and performance

system that works by dynamically changing properties and biomaterials. This would mean using gels

with elastic/peculiar viscosity properties and springs or damper systems together with natural materials

from nature which could provide safe high performance. But this is just a raw idea and needs

refinement.
