Sperry-Style Keds Boat Shoes Size 7/37.5/4.5

Basically new condition. Loved them and took for a walk, but they're too big. Would be happy to trade them for a pair of size 35-36 Sperry's (or similar) in new or very good condition, if you have any! Size US 7 EU 37.5 UK 4.5 -- too big for me! (Ideally seeking a women's 5.5-6 Sperry, but open to other offers!)
