Insoles Lab

We test our commitment to comfort

Material tests

All our materials are technologies produced and tested by Zahonero, which is an international company expert in developing advanced comfort solutions covering a wide range of technical applications, and which seeks to anticipate and respond to our clients’ needs.

Static tests

We conduct different static tests at our laboratory, under the most stringent quality standards. We have established a protocol to test each insole for comfort.
COMPRESSION LOAD DEFLECTION
Compression Load Deflection
_

Tests the material’s resistance to compression caused by the foot while walking.

STANDARD: UNE EN ISO 3386/1

COMPRESSION SET
Compression Set
_

Certifies durability of the material under very extreme conditions.

STANDARD: ASTM D3574 TestD (70℃-50%)

REPEATED COMPRESSION
Repeated Compression

_

Determines the life cycle of the insole with its characteristics at full performance.

STANDARD: SATRA TM156

CUSHION PROPERTIES
Cushion Properties
_

Measures the capacity of the material to distribute impact energy across a particular surface.

STANDARD: SATRA TM159 (Cushion Energy walking/running)

SHOCK ATTENUATION
Shock attenuation
_

Measures the insole’s capacity to mitigate impact on the heel. Shows the degree of protection for the foot and joints.

Measures the insole’s propulsion capacity in the metatarsal zone.

STANDARD: SATRA TM156

ABSORPTION/DESORPTION
Absorption/Desorption
_

Measures the amount of perspiration the insole can absorb and how long it takes to dry.

STANDARD: UNE EN ISO 20344

DELAMINATION
Delamination
_

Determines the force necessary to separate the insole material from the base.

STANDARD: UNE EN ISO 2411

Dynamic test

This test records plantar pressure using an instrumented insole system. It allows us to analyze the effect of the combination of the insole’s anatomical form and materials.
All insoles are analyzed following the same process guidelines (the same footwear, person, duration, step sequence, etc.) and the following aspects are compared with a test conducted without any kind of protective material on the insole:

  • Maximum pressure
  • Maximum pressure by zone
  • Maximum average pressure by zone
  • Reduction of average pressure
