A Brief Introduction To Asics

ASICS Logo

Asics (or Asics Global) is a famous Japanese footwear company. Asics was founded in 1949 in Kobe, Japan by Kihachiro Onitsuka, with the former name Onitsuka Co.

In 1970, Onitsuka Co. was changed to Asics. Up till now, Asics manufactures its shoes globally, with over 40% of its shoes made in Vietnam. Besides, there are factories in Cambodia, Brazil, India, China, Japan, and Indonesia.

ASICS is an abbreviation of an old Latin saying, “Anima Sana in Corpore Sano” (meaning “A sound mind in a sound body.”). This name is also the philosophy in all Asics products.

  • Apply top-notch technologies for runners’ experience: Asics understands that runners need high-quality shoes to maximize their performance. Thus, Asics’s R&D departments design shoes with new technologies to help runners move with comfort and safety. Some well-known technologies are cushioned GEL technology, Flytefoam Propel technology, and Guidesole technology.
  • Extreme durability: Asics shoes are for daily wear and can stand the harsh conditions of outdoor sports. These shoes are made of canvas, cotton, or polyester, so you can clean them in a washing machine and let them air dry. They can last up to 10 months if worn daily, or longer if worn less or worn as casual fashion shoes.
  • Aim for sustainability: Asics is also a shoe brand that is responsible for the environment. In 2018, this company reported that it’s going to lessen CO2 emissions by 33% and aim to 55% per product in 2030. Plus, this brand introduced an eco-friendly product called “Edo Era Tribute Pack” made from recycled PET bottles.

Useful Tips To Find Your Perfect Asics

Pick the shoe sizing based on your style

You should think twice about your desired sizing style. Some people love a loose-fit feeling, while others prefer a snug fit on their footwear.

Measure your feet

You should measure your feet length first to choose your most suitable Asics.

Place your feet on a piece of paper on the floor, with your heels against a wall. Use a pen to mark where your toes end on the paper. Then, measure the distance between your heels and your toes (or called your feet’ length). You can use this measurement to compare with the sizing chart of Asics.

Measuring your feet at the end of the day helps you get the exact measurement. In the morning, your feet tend to be smaller due to blood circulation and swelling.

Asics’s return policy

It’s normal when your sneakers don’t fit you, even after you have carefully done all measurements.

Luckily, Asics has a free return program to assist you in finding your perfect shoes. Every Asics shoe comes with a printed return card that you can stick onto the shoebox to send back to Asics for a full refund (tax included). To get this refund, your shoes must be new without any signs of use, and the product tags must remain.

FAQs

1. Do Asics running shoes have wide sizes?

While Asics doesn’t offer as many wide shoes as New Balance, it still has approximately 10% of its products in wide sizes and 15% in extra wide sizes. These wide-sized shoes are recommended for people with wide feet or those with foot-related conditions, like bunions.

If your toes roll over the sole’s edge, you have bulging, or over-stretching in the upper area, you also need to choose Asics wide shoes.

2. Should you size up Asics?

You should size up your Asics if the width between your toes and your shoes is less than half and a full thumb’s width. Bigger shoes let your feet have more room to move and expand when contacting the ground.

3. Does Asics Gel Kayano run small?

Asics Gel Kayano can run too small or true to size, depending on your foot size and shape.

4. Do Asics Nimbus 23 run small?

Asics Gel Nimbus 23 is a neutral shoe and it runs true to size. This product gives you a perfect fit from the toe box to the heel.

Conclusion

After answering the question “Do Asics run small or large?”, you are more confident picking up your perfect Asics.

Generally, Asics are true to size for women but slightly small for men. You should measure your feet and compare your number with Asics sizing chart to get your perfect ones. If you switch from another brand to Asics, you might also need to consider your current shoe size with Asics.

With all those considerations in mind, I hope your running experience with Asics is smooth and injury-free!
