Corky's Flirty CHAMPAGNE crystalS. We love Corky's flip flop sole shoes! This sandal will not disappoint with the Marshmallow soles and clean classy look. True to size. 3" cork wedge heel synthetic upper with stud accents. The footbed is comfortable and supportive, so you can wear it all day without fatigue. The stud accents add a hint of style and personality, while the cork wedge heel and sole make this sandal perfect for any occasion.
