Puma Vikky Shoes. Size 6.5. Like New

Puma Vikky V3. White with iridescent accent. Like New!! I bought these at Nordstrom rack and I thought they fit but I wore them literally once and found them too big. Never returned them- just sitting in my closet. These are the latest model with a soft foam insert. The size said 5.5 for kids (37.5 UK), but I’m a size 6 and this fits like a 6.5.
