I buy my sneakers for daily treadmill use.  Alternating two pairs, I generally purchase a new pair once per year.

Asics has always been a wonderful brand for my personal use.

However, I noticed the fit different from my other pairs.  They actually looked as if they were shaped differently as well. They are not as comfortable and I developed a blister on my first use.

Having somewhat broken them in, they will serve until replaced.

My older two pairs were made in China.  This new pair was made in Vietnam.

I would believe that the manufacturing guidlines and fit standards might not be the same.

In the future I will seek out Asics made in China.  Unfortunately, I have not yet found any sneakers that fit my use and are comfortable in the United States thus far.
