The shoe sole, found on the bottom of an athletic shoe, is where the foot meets the ground. It is usually made of carbon rubber, blown rubber or a combination of both. Carbon rubber is stiffer, lasts longer, and may be used in the high-wear areas of the sole, with the softer blown rubber in other areas.

What is a shoe sole?
Sole. The sole is the bottom part of the shoe. It is sometimes referred to as two separate pieces: insole and outsole. The insole is the part of the shoe that has direct contact with the bottom of your foot. The shoe’s outsole is the portion that contacts the ground when you walk.
What are Jordans soles made of?
Polyurethane (PU) appears in just about every sneaker you can think of, and it’s popular for a bunch of reasons. Not only is PU lightweight and flexible, it’s also pretty good at absorbing shock and resisting abrasion. It’s even relatively slip-resistant.
Which sole material is best?
PU :: Polyurethane soles are lightweight, resilient, flexible, and have good ground insulation and shock-absorbing properties. These soles have the best durability performance. RUBBER :: Rubber has excellent ground traction and is a non-marking, long-lasting material that enhances the shoe durability and longevity.
What type of rubber are shoe soles?
thermoplastic rubber
TRP soles. TRP soles are made from thermoplastic rubber. Manufacturers make thermoplastic rubber by molding and compounding rubber granules from raw materials that are in solid form. These soles are famous for their excellent shock absorption and slip resistance.
What are the different types of shoe soles?
- 5 Types of Shoe Soles You Need to Know About. 5 Types of Shoe Soles You Need to Know About.
- Rubber soles. These soles are made of organic or recycled rubber.
- Lugged soles. These are the kind of chunky soles you’d find on your hiking or utility boots.
- Christy soles.
- Camp soles.
- Cork soles.
Why do sneaker soles crumble?
Hydrolysis is the chemical breakdown of the PU polymer and the resulting physical breakdown or crumbling of the PU sole by the attack of water (usually in vapour form), occurring over a period of several years (even when the shoes are in store!). This process is accelerated by warmth and high humidity.
Why do Nike shoes fall apart?
Why Do Nike Shoes Fall Apart? Any sneaker worn often enough will accumulate enough damage to eventually come apart. Conversely, sneakers that are stored at length suffer from glues drying out and/or midsoles disintegrating. Shoes are made to be worn, and Nikes are no different.
How long do sneakers last before crumbling?
While shoes won’t start to deteriorate immediately after buying them, you should begin using them six to 12 months after your purchase. According to Stump, this is when they start to break down little by little. “It may not mean they’re completely unusable,” he says.
Which type of sole is most comfortable?
Cork Nitrile Soles
This makes it more lightweight and (subjectively) more comfortable than a lot of rubber outsoles, and it doesn’t wear down as fast as leather. It’s also much more wear resistant and oil resistant then leather — believe it or not, they much grippier than you’d think.
What kind of sole is good for walking?
A lightweight, thin sole, often found in walking shoes, will wear quickly and provide less grip but will be a lot more flexible and lighter weight. You will find some walking shoes will have the same soles as those found on walking boots. These sturdier soles will provide a higher level of traction and durability.
Which is better synthetic or rubber sole?
Rubber Pros: In general, a natural rubber outsole will give you a better grip than leather soles. They are pliable and offers reliable traction in both warm and cool weather conditions. High-quality natural rubber is also able to provide grip when exposed to oil and water.
What are most shoe soles made of?
The soles of men’s and women’s dress shoes are typically made from high-quality leather, rubber or a combination of the two. Casual, everyday wear shoes and work shoes often feature soles made out of natural rubber or polyurethane. Soles can be made out of one material or different types.
How many types of sole material are there?
We can summarize the latter in the following groups: Thermoplastic materials: PVC – TR – TPU. Two-component polyurethane materials: polyether-based PU – polyester-based PU. Copolymers: such as rubber and EVA.
How can you tell the sole material of a shoe?
Weight: RUBBER (rubber) is the heaviest, PU, EVA is the lightest. Material: PU is expensive, EVA, TPR is moderate, PVC is the cheapest.
How to identify various soles?
- PU is the lightest and most wear-resistant.
- The elasticity of TPR sole is better than that of PVC sole.
- The surface of TR sole is very bright.
How long do shoes last unworn?
That being said, I did my own research on some of the materials that are used in shoes, and I found that many materials do indeed have a shelf life. You can expect your stored, unused shoes to last for 2-3 years without issues if stored carefully.
What happens to sneakers when you don’t wear them?
Over time the fine leathers will begin to dry out, the rubber becomes brittle, the entire shoe forgets its purpose. If you decide not to wear a pair of shoes they never get to do what a shoe is meant to do!
What happens if you don’t wear shoes for a long time?
Shoes in the house
Not wearing shoes puts increased stress on the ligaments, tendons and around the ball of the foot, which need support and cushioning. “Without proper shoes and arch support,” says Dr. Weissman, “people are more likely to strain their arch, leading to plantar fasciitis.
Why do shoes break if you don’t wear them?
PU consists of long polymer chains that are gradually split apart due to the effect of moisture. As a consequence, PU loses flexibility over time and gradually becomes brittle. As the shoes reach an advanced age, this can lead to signs of disintegration in the soles.
Do Jordans have rubber soles?
One of the biggest takeaways is the evil of PU soles, an evil easily illustrated by the fact that the rubber soles in original Air Jordan 1s still render the shoes wearable today, while the PU from the following sneakers in the line means that an original pair of any other Jordans is almost guaranteed to crumble.
How long do Adidas shoes last?
A good rule of thumb is to get new running shoes every 300 to 500 miles, or roughly every four to six months if you average 20 miles per week. After thousands of steps in the same shoe, the cushioning in the midsole can become compressed, limiting its energy return and support.
