The number of technologies that are being used in shoes has increased over the past couple of decades. The use of memory foam in the inner soles of the shoes is a popular trend. The question that plagues most people’s minds is ‘What are the advantages of using memory foam?’.
To understand the advantages, one must first know a little more about the technology that is being used.
What is Memory Foam?
Memory foam is a substance that is made of polyurethane. There are a number of other chemicals that help add to its density. The foot molds itself to the contours of the material due to temperature sensitivity that the foam possesses.
Advantage of Using Memory Foam in Shoes
One of the main advantages of using memory foam is the even distribution of balance. While this helps provide a lot of comfort when used as a pillow or a mattress, you will find that it increases the comfort of the shoe too!
The memory foam is designed to ease the pressure that a runner feels on the ball of his foot. For that matter, everyone experiences this pressure even when walking. The intensity however is felt more when you run. In addition to this, the memory foam is also designed to absorb heel shock. Most manufacturers state that it also helps improve the stability of the shoe. This is why shoes with a memory foam insole are popular among people who suffer from foot pain.
Disadvantage of Using Memory Foam in Shoes
There a few disadvantages that memory foam insoles pose. One prominent one is the retention of body heat. Most sneakers are designed to be breathable. They are light and easy to use. Memory foam shoes however lack this ability.
Since the shoes do not have much of breathing space, the wearer tends to sweat. This makes the shoe feel particularly uncomfortable. To add insult to injury, the accumulation of sweat tends to give off a foul odor. Another unpleasant smell that is associated with memory foam is the off-gassing. New memory foam releases this odor. Experts advise airing the shoes before wearing them to deal with this.
Popularity of Memory Foam
Despite the drawbacks that memory foam possesses, the popularity of shoes with memory foam has steadily risen. The shoes seem to be more popular among individuals with foot problems like Plantar Fasciitis. Many experts advocate their use because they take away the stress from the plantar ligament.
Memory foam shoes are also popular among people whose jobs require long standing hours. Nurses, teachers, postmen etc all rank high on the list. Memory foam helps to take the stress of the feet and prevents pain.
The debate as to whether shoes which use memory foam are good or not continues till this day. A lot of people who have used these shoes can attest to the fact that they have helped them deal with pain. This is probably the base reason why the shoes have gained popularity. Since airing the shoes helps reduce the smell of new memory foam, most people choose to buy the shoes and deal with it.
For others memory foam either does not help to relieve their foot issues or it actually causes the the pain to worsen. So it works for some feet and not for others. But the memory foam shoes seem to be getting popular by the day.
