Thank you for viewing my listing! (^^) Immediate purchase is very welcome! Please take a moment to read my profile before purchasing or commenting. These are NIKE running shoes. My mother gave several pairs as gifts to my husband from her home. She said she didn't know his size, so she bought various sizes randomly (lol), and I'm listing the sneakers that didn't fit. These appear to be US 10, equivalent to 28 cm. They are new and unused, but I've already disposed of the box, so I will ship them in a bag I have on hand. Below is a description quoted from the official sales site: The Nike Initiator provides comfortable support for long-distance runs. Its breathable upper and soft, cushioned design help you run with confidence. Features Supportive overlays hold your foot in place. Soft lining for a comfortable feel against the skin. Foam midsole provides a soft, cushioned ride. Flex grooves in the outsole support natural movement. Product Number: HQ1179-001
