Eva and Zoe size 7-7.5 black platform Mary Jane toeless heels

Eva and Zoe size 7-7.5 black platform Mary Jane toeless heels. These are marked as a 7.5. I’m a true 7.5 and I feel like these run a little on the small side. The buckle on the strap does not unbutton- it is attached to elastic so it stretches when you put your foot into the shoe. Heel height is 5 inches. Platform under ball of foot is 1.5 inches. Shoes were worn one time for a wedding.
