Yes, those are the speckles that ASICS puts into their support material. It is completely normal and expected as this is the design of that material. The pattern is random and intentional. That material is only on the inside arch area of the shoe. The area in question is called the medial post area of the shoe and the speckles indicate a denser foam material for support. People do sometimes mistake those marks for dirt but it is part of the design of the shoe. I just want you to know that this is completely normal and those marks or speckles will be on every pair of ASICS support category shoes that includes the Kayano model among others.

要我翻译吗

对了楼主你这个材料从哪弄得？

强大的碉堡……

你好，因为我的店铺的顾客一直对于鞋底有黑点有疑问，可以借用你的官方这段话回复来用下吗？

C17没黑点 C系列就这样吗？

黑点的工艺是什么？求回复。
