With regard to the heels on our shoes, the heights mentioned on our website are indicative values. These are measured using a size 37 model and always on the inside of the heel so as to reflect the height perceived at the level of the arch of the foot and the rest of the body. Please note that there may be a difference of up to 2.5 cm between a size 37 and a size 41. Furthermore, there may be a difference of 2 or 3 cm between the height calculated on the inside of the heel and that calculated on the outside for the same shoe size, since on the outside, the height of the sole is taken into account, but this is not reflected at the level of the body.
