These are carbon plate running shoes from the Chinese manufacturer XTEP (Tebu). They have been used for approximately 20 kilometers and are men's size. The size is US 8.5, EUR 41.5. I purchased them new from an online store. The size is a bit large, slightly bigger than 26.5 cm in Japanese size. I only used them twice when I first bought them, but I have too many shoes and no longer use them, so I am selling them to declutter. Please check the images carefully to assess the condition of the shoes before considering a purchase. They have been home-cleaned and come with the original box.
