These are Asics boxing shoes. They've been discontinued, making them difficult to find. I purchased them from a flea market site before summer, so the frequency of use is unknown. I bought them as size 26.5cm, but I think they might be 27cm. I usually find Mizuno 26.0cm a bit tight, and 26.5cm has a little room. However, these shoes felt a bit roomy on me, so I suspect they are larger than 26.5cm. The tag has been cut off and is not remaining. For reference, I wear 26.0 or 26.5 in sneakers. These shoes felt a bit large. I wore them once at the gym and they didn't slip. They show considerable wear, with hardened rubber and cracks in the lines, but I think they can still be used as a second pair. Due to the above reasons, I am selling them at a low price, and returns are not accepted. They will be shipped in a bag, not a box.
