These Acne blue heels feature a sleek mule design with a sophisticated square toe and a decorative bow detail. The vibrant blue color and satin-like finish add a touch of elegance, while the slim 2-3 inch kitten heel offers a comfortable lift. Perfect for formal occasions, these slip-on shoes combine style and ease with their open back design. Purchased and verified authentic from Vestiaire. Worn once to work for about 5 hours, realized it was a size too big. I’m a 7.5-8, these would fit an 8.5-9 (IT 39).
