Traumatic injuries

Are caused by an acute external force which exceeds the maximum durability of a tissue(bone, muscle, tendon, ligament)during one specific event, such as a tackle or high impact force. A one-off high load, such as those found in tackles of collisions, applied to a region can cause structural failure in tissues – this is also true for lower loads that are repeatedly applied.

Metatarsal injuries

Are the most common traumatic foot injuries causing debilitating pain and lost sports time.

The Metatarsus consists of the five long bones of the foot, which are numbered from the medial side. The larger of these bones, the OS metatarsale 1 is the most exposed is more likely to be damaged. This bone is the metatarsal attached to the “great toe” or big toes and the bone that is responsible for distribution of weight when walking. The remaining four bones, OS metatarsale 2 – 5 are attached in turn to the remaining four toes of the foot and assist with balance when walking. These bones are protected by Zock to reduce or prevent injury.

Metatarsal injury facts:

  1. Is a devastating personal injury
  2. Painful and debilitating
  3. Required long term rehabilitation process

Proximal fifth metatarsal metaphysical fractures (PFMMF) have been reported with increasing frequency in athletes.




Several studies have reported that PFMMFs are challenging to treat. Furthermore, healing problems, delayed union and re-fractures have been shown to occur with PFMMFs. Although fifth metatarsal fractures often occur, thereby increasing the probability of a re-fracture especially in athletes who return early to sporting activity, to the best of our knowledge there are no reports of techniques or methods to prevent these fractures.

The Football Medicine And Performance Association also stated "the Zock is able to reduce shock up to 40% without impacting the players ability to pass or shoot the ball" 


Research was conducted by The University of Central Lancashire, at the Allied Health Research Unit in 2017.
