Musabela comfort shoes

I have two brand-new Musabela sneakers with removable insoles that are a bit small for me. It would cost more than it's worth to return them. They are EU sz 11, but I find that they fit more like a 10.5 than an 11 in length. My feet are between narrow to medium. I find that they fit well in the toe box and width. Both pairs are available for $80, but I will sell them separately for $40 as well. PLEASE feel free to make an offer.
