Dsquared2 DSQUARED Beach Sandals Size: 41 (Actual size 27.5cm) I usually wear 27.5cm in Nike and Adidas (sometimes 28cm if I want a slightly looser fit), and these fit perfectly. Purchased from an authorized retailer and stored after only being tried on. The soles show no wear, so they can be worn like new. There is a slight warping characteristic of beach sandals due to storage, but it should flatten out with wear. Please refrain from purchasing if you are overly concerned about this.
