Game Changer Football Boot

Problem Definition

Traditionally, football at all levels was only played on grass meaning that football players only required one pair of football boots.

These days, however, footballers can expect to play on a variety of surfaces, each of which require a different outsole to ensure optimal surface/boot interaction. Children and amateurs footballers in particular play on a variety of different surfaces (grass, astro grass, astro turf, gym halls) and therefore need to buy several different pairs of boots/trainers to ensure optimal surface/boot interaction. This can be very expensive especially for parents who may have more than one child requiring several new pairs of boots every year.

Design Solution

The Game Changer is a pair of football boots consisting of an upper part and an interchangeable outsole. This means that a player only has to own one pair of uppers with different outsoles to play on all surfaces (as opposed to several pairs of boots they would currently need to own). With this revolutionary football boot they will save money by only having to purchase one pair of uppers and then purchasing whatever other outsoles they require depending on the surfaces they frequently play on.

The customer will receive 1 pair of boot uppers and 1 pair of interchangeable soles. They will then be able to purchase other outsoles separately. There will be 5 different outsoles available in a variety of styles and colours.

User Interaction

Putting The Boot On

First the user puts on the upper and then stretches the outsole attachment (shown in graffiti red) over it aligning the tread patterns that are on the bottom of the upper with those on top of the soleplate. These tread patterns will restrict lateral movement between the upper and the outsole attachment.

The elastomeric attachment is then pulled over the latch at the back of the upper. When released, the attachment will sit perfectly in place preventing the attachment from sliding downwards.

Finally the laces are then threaded through the corresponding eyelets on the outsole attachment. The laces are tied tight to provide extra stability between the outsole attachment and the upper. With this system, attachment should take a matter of seconds as opposed to the 5+minutes it would take to change a set of studs on a regular pair of football boots.

Hidden Lace System

To improve the quality of contact between a player’s boot and the ball, a hidden lace system was devised.

The design requires the boot to have two tongues. The foot is protected from being in direct contact with the laces by the inner tongue.  The outer tongue is used to conceal the laces. Velcro at the sides of the outer tongue (shown in figure 1) is attached to Velcro sewn inside the upper (shown in figure 2 next to the eyelets). Once attached, the laces are tied and hidden behind a flap at the top of the outer tongue (shown in figure 3).
