SATRA-accredited test lab

At Safety Jogger Works, we thoroughly test every product in our SATRA-accredited laboratory. Working closely with SATRA, an independent leader in research and testing, we built our lab to the highest standards.

Their expertise in equipment, calibration, test methods, and ongoing training ensures we can consistently evaluate our products and drive continuous improvements in quality, safety, and performance. 

Watch the video below to see how we put every safety feature to the test:

Upper & fabric material performance
Fabric abrasion resistance

To ensure that the materials used on our shoes meet our quality standards, we test their resistance against abrasion by subjecting the materials to repeated friction and checking material durability.

Fabric pilling resistance

This test checks how well a fabric resists to wear and friction. The material is rubbed against another piece of the same fabric to see how it holds up to everyday wear.

Tear strength

This test measures the force needed to tear flexible materials. The sample is pulled apart until it tears, revealing the material’s strength and durability under stress.

Lace-to-lace/lace-to-eyelet abrasion

Shoelaces are tested for durability by rubbing them under tension against other laces or eyelets until they break. This process shows their resistance to friction and ensures long-lasting performance in daily use.

Suter (water penetration) test

This method measures the water pressure resistance of waterproof fabrics and materials. By applying water pressure to the material until penetration occurs, we can precisely determine its level of water resistance and ensure reliable protection in wet conditions.

Toe cap & impact protection
Impact resistance

All Safety footwear needs to withstand an impact force of 200 Joules while keeping enough clearance to protect your toes. This is tested by dropping a standardized weight of 20kg on a finished shoe, from a height of 1 meter.

Toe cap compression resistance

At the component level, toecaps are also tested for compression resistance to ensure protection against heavy loads. During this test, a gradually increasing static compressive force is applied to the toecap until a load of 15 kN (approximately 1.5 tonnes) is reached. This test complements the impact test, verifying the toecap’s overall structural strength and deformation behaviour.

Outsole performance & durability
Outsole abrasion resistance

We verify to what degree the outsole material abrades when being used on rough and hard-wearing surfaces, to ensure that the shoes meet both the official standards and our internal quality requirements.

Outsole energy absorption

We evaluate how well the outsole and midsole absorbs energy during impact. Using the EN ISO 20344 5.17 energy absorption test, we measure how effectively the footwear cushions shocks to ensure comfort and reduce fatigue.

Outsole penetration resistance
We test the outsole’s ability to resist sharp objects such as nails or metal fragments. This ensures that no object can pierce through the outsole.

Outsole flexing resistance

The outsole is flexed at a specific speed and angle to assess its flexibility and endurance. This ensures long-lasting performance and comfort during movement.

Outsole slip resistance

To ensure maximum grip and avoid accidents due to slipping, we test the friction of our outsoles on different surfaces according to EN ISO 20345:2022. The standard includes:

  • Mandatory test (formerly SRA): Resistance test on ceramic surfaces with a soap solution.
  • Optional SR rating: Additional test on ceramic surfaces with glycerine for a higher level of slip resistance.

Whole-shoe flexibility and water resistance
Full shoe flexing resistance

This test measures how well a complete shoe withstands repeated bending during walking. It helps detect weak points such as sole cracks or separation, ensuring durable and comfortable footwear.

Water resistance
This test evaluates the degree of water resistance of our safety shoes and boots. We flex the footwear in a water bath at a constant rate and inspect if there is water penetration.

Electrical and static protection
Electrostatic discharge

This test determines if our footwear complies with the electrostatic discharge standards (ESD).  ESD footwear protects sensitive electrical equipment by safely controlling the release of static electricity.

Electric hazard (18 KV)

We check if the shoes are electrically insulating to protect the wearer when being subjected to a voltage up to 18kV.
