Thank you for viewing. I purchased these in bulk, but I haven't had the opportunity to use them. They are new, unused, and have been stored at home. According to Mercari's shoe size chart, size 41 corresponds to 25.5 cm. These are navy suede slip-ons with white stitching. - Color: Navy - Material: Suede - Design: Slip-on - Features: White stitching - Brand: Escadrille Thank you for viewing.
