Betsy Johnson white sneakers with blue, sparkly flowers 6.5

Betsy Johnson sneakers, white and blue floral. These are super cute and I love them, but they are too big! I typically wear between a six and 6 1/2, and went with a 6 1/2, but are way too big. I've worn these once. These have a slight platform. Maybe half an inch. Smoke free/pet free home
