Shin Guards

2. Fastening of shin guards to the players' legs

Initially, shin guards were fastened to the players' legs by means of belts. This method did not only impair the free movement of the leg but also reduced blood circulation in the calf area and led to early fatigue and cramps.

An early British patent specification (GB 1886-2678) proposed to hold shin guards in place by means of elastic springs to avoid cutting off circulation in the wearer's calves.

The easiest way, avoiding straps or lacing, is to put the shin guard into the socks. The drawback of this solution is that these shin guards will easily slide on legs wet with perspiration. To avoid this inconvenience, the inside of the shin guard is usually coated with a gripping layer so that the shin guard will not slip out of the sock (Figure 3a).

Other shin guards have fork-like extensions at the lower end which cover the ankles (Figure 3b). These shin guards are less prone to lateral sliding and additionally protect the ankle from blows (cf. section 4).

The grip of socks/stockings/gaiters to the legs is a general problem. Wet, slipping gaiters, above all, will not retain shin guards sufficiently in position, so that the shin guards will easily slip out despite a gripping layer. It was therefore proposed to incorporate shin guards into the socks or to insert them into specifically provided pockets (Figure 4). These solutions will only work if the socks fit well and tightly to the legs, which cannot always be guaranteed, especially under wet weather conditions.
Furthermore, cleaning and care of such reinforced and mostly expensive socks are comparably cumbersome.

Owing to these difficulties, the most popular fastening method still consists in attaching shin guards by means of flexible calf straps. In the early days of football, laced or buckled straps were typically used for fastening shin guards. A maybe somewhat cumbersome solution had been drawn up in the 1920s. It consisted of two longitudinal shin-guard halves reinforced on both sides by means of celluloid or steel bars. The parts were laced together at the front and fastened to the wearer's leg by two calf straps.
Flexible calf straps provide easy to remove and adaptable fastening solutions. The previously used buckles have been replaced by hook and loop fasteners.

A very popular solution for fixing a shin guard consists in the following: a gaiter-type component is placed around the ankle area so that only one calf strap is required to hold the protective shell in place. Apart from being placed in pockets, protective pads or shells can be attached by means of slip-on or clip-on solutions (Figure 5). Again, cleaning and care must be considered. The detachable fastening of rigid shells on soft fabric gaiters offers significant advantages.

Most recently, shin guards were proposed, in which a protective plate with spiral springs is attached to a leg protection cover (DE 10 2011 052 970 A1).

The self-holding shin guard GB 2 484 570 A1 should do completely without socks or belt.
GB 2 506 414 A is a further development of the sock with integrated shin guard and additional fastening element.
DE 20 2016 101 863 U1 makes improvements to a neuralgic point of the shin guard, the anti-slip material on the inside and fixing surfaces on the outside.
