Women's size 8 long Dr Martens platform sandals black and white

Women's black and white platform sandals Dr Martens size 8 long usa. I'm a size 7 and they fit okay, but my toes didn't go much past the straps and were a little wide. I can also sometimes wear shoes a little smaller or a little bigger depending on how they are made. It seems even though they are a size 8, they were a little big and could also easily fit size 9 to 10. They measure around 10 inches long.
