I bought my shoe at the boulevard mall in La's Vegas before new years, and i tried it on but i found some negative things in it, for example when i put the shoe on my right side toes start to hurt, and when i bought the shoe it look liked it was used. I accidentally threw away the receipt. I was freaked out because i cant go to the store 'till January 2. Sooo is it still possible for me to return these shoes without a receipt?
