On Cloud Cloudnova Running Shoes

I got these for On Clouds for my birthday and they are a size too big. They are the On Cloud Cloudnova running shoes. I don’t have to original box because I think it got thrown away along with the wrapping paper. But I have never worn these except to try them on, I am hoping to find a new home of them. If you have questions or would like additional information let me know! I am open to offers!
