These are new, unused running shoes with tags attached. The brand is adidas. The model is Duramo Speed 2M from the adizero series. The size is 28.0cm, and the "M" indicates it's a men's model. The color is black with red stripes and a bit of blue on the back. While it might not be a high-end model, cheaper models are sometimes not included in the adizero line, so I recommend this for those who find this price range suitable. I cannot explain the functions or structure, so it would be best to research them online. This listing includes shipping, so please purchase early. I do not offer personal discounts. The box and internal paper may have some damage. I am also selling other guitar-related items at great prices. ↓ Other items in the same size: #Apache28cm Gender...Men's
