Geox Leather breathable Sandals

Listed as size 26 and size 9?? On Geox website but it runs small because of extremely supportive hill/back of the sandals that push little foot frontward. That is why we did not get wear it much. Please note the pictures with measurements. I don’t think it would fully fit 6.125” foot. Rather 5.75”, which would be about size 7.5-8US
