Silver BCBGeneration Gladiator-ish Heeled Sandals

Really pretty silver BCBGeneration peep-toe sandals. They have been worn and have some minimal wear around the shoe but none really on the soles. They are a size 6B, with a 2 inch heel. They are a little too big for me so they nip at the back of my heel when I walk in them (I am a size 6, not sure whether M or B) (These shoes have been in a home with a dog, for those with allergy concerns. Non-smoking.)
