Absolutely love these booties but they are 1/2 size too small for me. They are stamped EU size 38, which is a US size 7.5 or sometimes an 8 if your feet are on the narrow side. I have this style in MM LaFleur's pump and they are super comfortable and easy to walk in. Official description "Made using a low-waste 3D knitting process, the Lana features an extra-supportive footbed, natural odor resistance, and a 3-inch scratch-resistant heel. Thanks to their 3D knit construction, these shoes will mold to the foot and feel like they were made just for you—with incredible stretch and recovery." Feel free to ask any questions.
