Cape Robbin Slip On Sandals/Mules In Festive Blue Size 6 (Fits Like 7/7.5) BNIB

Cape Robbin slip-on summer sandals/mules. Box says Size 6 (USA), but I think they run big. I normally wear an 8, and I thought I could wear these, but they are too tight on my foot. I think they are best fit for a Size 7 or 7.5). Color is festive blue. Batch number BM8069-9. Shoes are brand new in box and have never been worn. From a smoke-free and pet-free home.
