Thank you for viewing. This is the NIKE INFINITY RUN 4 WIDE. I have been using these for everyday wear. The running distance is about 10km. These are Nike's popular running shoes, the "ReactX Infinity Run (Wide Model)" (retail price 18,700 yen). The color is black, and the size is 25.5cm. Below is the product description. I purchased these new from a Nike store, and then purchased them here. Please note that the top of the box is cut off because it was a last stock purchase.
