Principles of footwear testing:
series index
An in-depth consideration of the many test methods used to assess the properties and predicted performance of footwear materials, components and finished footwear.
- Part 1: Abrasion of uppers/lining
In this first article on footwear testing, we investigate how to test for resistance to abrasion.
- Part 2: Testing for colour fastness
Investigating the ability of a material to retain its original colour when subjected to various influences.
- Part 3: Flexing
Valuable test methods used to assess the durability of footwear upper materials and surface finishes.
- Part 4: Strength
A consideration of test methods designed to assist shoemakers in selecting materials.
- Part 5: Water vapour permeability
Assessing a material or whole shoe for water vapour permeability.
- Part 6: Sole abrasion resistance
In the latest part of this series, we examine abrasion test methods for sole materials, top-pieces and whole soles.
- Part 7: Sole flexing
An examination of shoe bottom test methods for sole materials and whole soles.
- Part 8: Strength of soling materials
Considering a variety of test procedures used to assess this vital footwear component.
- Part 9: Laces
Often viewed as a simple component, the lace actually plays an important role in the footwear's success.
- Part 10: Box toes and counters
Shape – often provided by the box toe and counter – is a highly important characteristic of footwear.
- Part 11: Shanks
Shanks are a vital source of hidden support in footwear, and their failure can lead to serious consequences.
- Part 12: Zips
Each component in a zip must function satisfactorily time after time over the life of the footwear.
- Part 13: Insole strength
Testing to assess the general quality of this vital footwear component.
- Part 14: Durability of insoles
This article covers two aspects of durability: resistance to flex failure and abrasion resistance.
- Part 15: Lace carriers and facings
A review of the various test methods used to test the physical properties of eyelets and other lace carriers.
- Part 16: Touch and close fasteners
How these commonly used components can be tested as to their fitness for purpose.
- Part 17: Whole footwear adhesion
Considering the importance of assessing material bonds used during footwear production.
- Part 18: Bonded assemblies
How to prepare and test bonds in the laboratory.
- Part 19: Elastics
Assessing these commonly used materials to establish their elasticity and durability.
- Part 20: Straps/buckles
Considering methods to evaluate the fitness for purpose of these vital footwear components.
- Part 21: Reinforcement
How footwear tapes and reinforcement materials can be assessed.
- Part 22: Trim attachment
If poorly attached, a trim can cause major problems.
- Part 23: Security of decoration
Assessing fitness for purpose of some decorative trims can present a challenge.
- Part 24: Threads
Examining the assessment of stitching thread used in the production of footwear.
- Part 25: Heels
Investigating how heels for women’s shoes are assessed.
- Part 26: Insocks and footbeds
Considering a number of test methods used to assess these key footwear components.
- Part 27: Metallic components
Assessing such components can help to identify tarnishing and corrosion problems and so avoid complaints.
- Part 28: Top-pieces
How top-pieces for men’s and women’s shoes are tested.
- Part 29: Studs
Considering the assessment of these important components which provide grip on footwear for popular sports.
- Part 30: Slip resistance
Slip resistance testing applies to virtually every type of footwear.
- Part 31: Thermal properties
Footwear must keep the wearer’s feet at a comfortable temperature.
- Part 32: Seams/seam holding
There are various different types of seams used in footwear manufacturing, all of which should be tested.
- Part 33: Water resistance testing
How can the ability of footwear materials and whole shoes to resist water ingress be assessed?
- Part 34: Whole shoe flexing
This month we will discuss the methods used for testing whole footwear for flex resistance.
- Part 35: Backparts
Considering test procedures employed for the assessment of these important footwear components.
- Part 36: Causes of discolouration
Footwear that discolours can lead to retailers rejecting stock and customers returning their purchases.
- Part 37: Propensity to discolour
Some of the tests that can be carried out to determine whether materials have the propensity to discolour.
- Part 38: Deterioration
Predicting the likelihood of footwear being susceptible to damage during shipping, storage and use.
- Part 39: Shoe care products
Assessing the effectiveness of substances designed to clean or protect footwear.
- Part 40: Packaging
Tests to assess the effectiveness of this vital protective element in the delivery of finished goods.
