The truth about technology - Cushioning

The running industry has rapidly evolved over the past decades, continually introducing new brands, new shoes, and new technologies. As a runner, it can be difficult to navigate this ever-growing marketplace in order to clearly find which shoes are best suited to our incredibly unique needs as individual runners. The shoes we wear dramatically influence the way we run. They affect our technique, our performance, and most important of all, our risk of injury. That&#;s why choosing the &#;right&#; shoes is so important.

You can find more information on our web, so please take a look.

Runners are exceptionally unique, which means that every runner has their own different technique, body shape, ambitions, and philosophies. Meaning that finding and choosing the right shoe can be an overwhelming and inconsistent experience.

In this series, we will dig deeper into three of the most utilized technologies in modern running shoes. These are Cushioning, Plates, and lastly Stability.


The history of cushioning

Cushioned shoes or maximalist shoes are characterized by the firmness of the foam in the sole and thickness of the shoe between your foot and the ground. This material usually helps to absorb the impact when your feet touch the ground and may provide comfort. Minimal shoes have very little or no cushioning and a height of less than or equal to 16mm.

The cushioning can be placed at each part of the sole, where it can be thick at the whole surface, only at the rearfoot or only at the forefoot. This will affect the heel to toe drop, which is the difference in height between the heel and forefoot. There are four categories of the heel to toe drop: zero drop (0mm), low drop (1-4mm), mid drop (5-8mm) and high drop (8+mm). A high drop promotes a rearfoot strike whereas a low drop a more mid/forefoot strike. In general, the lower drop will load your ankles and Achilles more, whereas the higher drop will load your hips and knees more.


Famous cushioning shoes

Many shoe brands are well-known for their cushioning technology. This article will focus on the following three running brands: Adidas and their Boost technology, Asics and their GEL-system and lastly Nike with the ZOOM technology.


Adidas Boost was introduced in , with the first pair of Energy Boost running shoes. Boost consists of small energy capsules which together form the foam of the midsole of an adidas Boost running shoe. The midsole helps to save energy during impact and will return this energy when the feet of the runner hits the ground. Other benefits from the Boost technology are that the shoes cope with a wide range of temperatures for both hot and cold weather. The technology is durable and flexible and lastly, the comfort of the cushioning. A great example of an adidas running shoe series with Boost technology is the adidas Ultraboost series.



ASICS introduced their GEL-system in , with their first pair of running shoes, the GT-II silhouette. The GEL-system consists of GEL that is placed at both the forefoot and rearfoot of the running shoe to reduce the impact during heel strike. The rearfoot GEL allows a smoother transition of the foot, whereas the forefoot GEL helps to reduce the shock impact during running. Besides the rearfoot and forefoot GEL, the GEL-system increases comfort over longer distances but also gives softness and comfort for optimum performances. The Asics GEL-Nimbus series is a great example of running shoes that have the GEL-system.



Nike has their famous ZOOM technology that exists since , that is located in the foam of the running shoe. ZOOM is pressurized air combined with tightly stretched fibres that combined help to reduce the impact. ZOOM can be very helpful when a runner wants to be faster and wants to reduce stress on their body. Speed, responsiveness, control and a decrease in pronation while running are other important benefits of the Nike ZOOM technology. The ZOOM technology has been used for the attempt to break the Sub 2 hour for a marathon (running a marathon under 2 hours), which Eliud Kipchoge broke in October using the Nike ZOOM Alphafly, a Vaporfly prototype.


How does cushioning work?

Cushioned shoes are highly debated over the last years, where the effect on the running economy and risk of injuries vary a lot for every runner. For example, long-distance runners need cushioning to reduce injury risk due to the number of impacts over the run.

Furthermore, rearfoot strike runners have a more abrupt impact force when landing compared to runners with a forefoot strike and usually benefit more from a shoe with heel cushioning. Subsequently, forefoot strikers have fewer benefits from a lot of cushioning, because the cushioning is not used and unnecessarily makes the shoe heavier at the heel. They are more likely to benefit from minimalistic shoes.

PU Sole Safety Shoes: A Comprehensive FAQ Guide - Aimboo

Have you been thinking of starting a PU Sole Safety Shoe business but are confused with certain aspects of it?

In that case, this guide is specifically for you.

We have provided deep insight to all the frequently asked questions regarding PU Sole Safety Shoes and hope that you will find the solution to your query here.

Continue reading this guide and untangle the knots in your brain.

What is a PU Sole Safety Shoe?

Polyurethane, also known as PU, is a light and highly abrasion-resistant material that is perfect for an occupational safety shoe sole as it is really affordable and durable at the same time.

PU Sole Safety Shoes are usually preferred for hard labor and a strict working environment that requires quick movement and being on your feet for extended periods of time.

Since soles are a part of the safety shoe that is in direct contact with the ground, they are more prone to wear and tear and even potential hazards at the workplace; however, PU Sole Safety Shoes are specifically designed to overcome all these barriers and make your professional life a bit easier and less strenuous.

PU shoes are generally known as sports shoes and are great for trekking and running but have now become common in the safety shoe industry.

Is Rubber or PU Sole Better?

Rubber sole safety shoes are more suitable for an indoor setting, while PU Sole Safety Shoes are designed for an outdoor environment.

Rubber soles may show signs of wear and tear after being worn for long periods of time and are also not suggested to be worn daily.

On the other hand, PU soles are incredibly durable and can be worn for extended periods without causing discomfort or swelling to the feet.

For sole, you require a material that is hard enough not to let sharp objects pierce through your skin but soft enough to not provide cushioning and comfort while walking.

PU sole lives up to all these requirements, whereas rubber soles are permeable and can also absorb oil.

Why is a Polyurethane Sole Considered Good for Safety Shoes?

A polyurethane sole is known to provide unmatchable breathability, cushioning, and traction on all sorts of surfaces, which is why many people prefer them as an outsole for their safety shoes.

It is also highly flexible and provides room for a lot of movement, which means that they can adapt to any surface due to their flexibility and can provide maximum protection.

A PU Sole is also wear-resistant, which means that it does not show signs of withering away and is also not prone to tearing, which is a big plus point for safety shoes.https://www.youtube.com/embed/1RgAfBdgs8E?feature=oembed&wmode=opaque

Should I Choose PU Sole, PVC Sole, or TPR Sole for Safety Shoes?

The choice regarding which sole to incorporate in your order of safety shoes depends on the kind of work environment you possess.

Different soles serve different purposes, so they can only be judged based on their functions in their respective workplaces.

PVC soles, also known as polyvinyl chloride, are great for insulation and shock absorption and can be worn daily without the hazard of wear and tear; however, they are not the most comfortable soles and can not be used for quick movements, and would weigh you down while performing tasks.

Similar is the case with TPR soles, also known as thermoplastic rubber.

Even though they are still better than PVC soles as they possess excellent shock absorption and are even slip-resistant and water-resistant, and also maintain a firm grip, they are still more fit to be worn during adventures and not as safety shoes as they are not comfortable and can not be worn on a daily basis.

Hence, our experts would suggest you choose PU sole as they possess all the beneficial characteristics mentioned above and do not compromise on safety.

What are the Characteristics of PU Sole Safety Shoes?

PU Sole Safety Shoes are organically produced and hence, do not contribute to worsening the environmental conditions.

They also possess excellent shock absorption along with wear and tear resistance which makes them an in-demand product in the business industry.

  • Have two pairs of PU shoes to wear in alternating days, also clean the interior part, remove the insole and dry.

Is PU Sole Slippery?

PU sole offer good grip in any surface hence they cannot slip in wet or watery surfaces.

This slip resistance feature is a minimum requirement for all safety shoes according to the European standards EN ISO standard.

This standard requires safety shoes to have at least one type of slip resistance feature rated as SR, SRB or SRC.

  • SRA is slip resistance rating against ceramic floor wetted with diluted soapy liquid.
  • SRB is anti-slip rating tested on smooth steel wetted with glycerol.
  • SRC is a slip resistance rating for PU sole shoe that have both SRA and SRB properties.

What is Hydrolysis and How does it Relate to PU Sole Safety Shoes?

Hydrolysis is a chemical process in which water breaks down chemical bonds in the PU material resulting into PU crumbling overtime. This process is facilitated by water in vapor form and sped up by warmth or high humidity.

PU sole safety shoes can be made by either Polyester based PU or Polyether based sole.

Polyester based PU have low hydrolysis resistance and high oil resistance while vice versa for Polyether based PU sole.

Most safety footwear manufacturers use Polyester based PU sole in their PU sole safety shoes. These shoes normally last for about 1.5 years in tropical areas and 4 years in normal weather conditions.

Technology advancement has made it possible manufacturers to extend resistance to hydrolysis for the Polyester based PU soles.

The resistance to hydrolysis has been improved to 3 years and 8 years for tropical and normal climatic conditions respectively.

What are the Certified Standards for PU Sole Safety Shoes?

PU sole safety shoes observe two major certified standards namely; ASTM  and EN ISO .

ASTM stands for American Society for Testing Material and it&#;s an international body that defines and publishes voluntary technical standards.

ASTM has two certifications to be met under F and F that were adopted in .

ASTM F is the standard for performance requirement while ASTM F defines standard for safety testing method.

ASTM F standard differs from other standards due to its mandatory need for shoes to be entirely insulated against electric shock. Other performance requirement standards include; puncture and impact resistance.

EN ISO -11 is the adopted European safety standards for protective footwear and was updated in . This standard states that all safety footwear must have a front toe protection of about 200 joules.

The EN ISO has other safety standard classes coded as S1-S5 with each defining the safety feature it provides.

Buyers of the PU sole safety shoes can use the safety data sheet to guide them in selecting the right shoes.

What are Electrical Hazard Rated (EH) PU Sole Safety Shoes?

Electrical hazard rated (EH) PU sole safety shoes are made using non-conductive material to prevent electrocution. They do not allow electric current to pass through the body from the ground thus protecting the wearer.

EH PU sole safety shoes are also known as isolating safety shoes because they isolate you from the conductive ground.

Electrical hazard rated shoes are tested against the ASTM standards before they can be certified as EH rated shoes.

EH rated safety shoes differ from ESD shoes in terms of performance and protection offered. While EH rated shoes prevent electric current conductivity through the body, ESD prevent static charge build up.

EH rated shoes can lose their protective feature if the sole wears out and if used in wet areas. They should therefore be strictly used in dry workplaces and replaced immediately the sole wears out.

Which is better between Antistatic Safety and ESD Safety for PU Sole Safety Shoes?

Antistatic and ESD (Electrostatic Discharge) PU sole safety shoes provide protection against static shock, charge or spark. Static shock is caused when static electrical charges buildup in human body leading to flow of electric current between electrically charged objects.

Such incidences are common in industrial manufacturing industries, battery industries, aerospace, hospitals, telecommunication equipment manufacturers, etc.

Antistatic and ESD PU sole safety shoes are made from conductive material which conduct static electric charges into the ground.

Antistatic safety shoes provide contact electrical resistance of 0.1 to Mega Ohm (MΩ). It accomplishes this by conducting the static charges into the ground thus preventing build up and electric current flow through the body.

ESD safety shoes offer lower electric resistance of 0.1 to 100 (MΩ). They safely conduct the flow of static charges into the ground.

Unlike antistatic safety shoes that just conducts charges into the ground, ESD safety shoes does it safely and in controlled way.

It also offers protection against a wide range of harmful static electric charges that may lead to shock or explosion. Workers can use ESD or antistatic safety shoes when working in industries where static electric charges are common.

They can wear ESD PU sole safety shoes for better protection.
