SAK Project / The first shin guards with optimum fit

Shin guards are a mandatory piece of equipment for every football player, yet they often cause fit and comfort issues. In 2015, the SAK Project introduced a new concept that addresses these problems by basing shin guard selection on leg diameter rather than just size.

What Does SAK Stand For?

SAK stands for Safety Against Kicking, clearly defining the brand’s focus on specialised player protection.

The Development Behind the MORPH Model

The MORPH model was released after several years of development, testing, and improvement with the help of professional football players from top clubs worldwide, including Real Madrid CF, Chelsea FC, Manchester United, Tottenham Hotspur, Juventus FC, FC Zenit St. Petersburg, FC Porto, Valencia, Benfica, Sporting Lisbon, and many more.

Why Traditional Shin Guards Fall Short

Development work by SAK revealed that lower-end shin guards provide inadequate protection, creating a false sense of safety with low-quality, cheap materials. Carbon fibre shin guards, while highly resistant, are very stiff and uncomfortable in fit. These shortcomings drove the SAK Project to develop revolutionary shin guards.

Materials and Certification

SAK shin guards are produced with high-quality materials and the latest production techniques, making them lightweight, flexible, tough, and highly resistant to impacts. The product is the result of collaboration among elite specialists: professional football clubs, sports doctors, and technological researchers.

  • Exterior protective polymer art layer used in the military and aerospace industries.
  • Inner cushioned layer with high impact energy absorption capacity.
  • European Certification EN 13061, covering impact tests and skin compatibility.

The Shape Revolution: Leg Perimeter Scanning

What truly sets SAK shin guards apart is their shape. Traditionally, players choose protection based solely on size (bigger or smaller for the tibia). SAK offers three standard sizes (M, L, XL), but the real innovation came from scanning the leg perimeter of hundreds of football players.

Three Leg Types for the Perfect Fit

The scanning led to the identification of three leg types:

  • Thin – Less than 34 cm leg perimeter. Designed for thin muscle and bone structure, where other shin guards would be too large, creating empty spaces.
  • Regular – Between 35 and 40 cm leg perimeter. Designed for a medium leg perimeter, where other shin guards can feel too tight. Optimum fit with flexible and tough materials.
  • Wide – More than 40 cm leg perimeter. Designed for wider leg perimeters, where other shin guards will not offer a comfortable fit.

The result is a product that differs significantly from other shin guards on the market:

  • Flexible material that adapts to leg movement.
  • Thin profile.
  • Seamless construction.
  • Inner textile layer for extra comfort.
