The height of the shoe from the number 34 to the number 41 physiologically undergoes a slight difference in height.
The slope of the socket varies slightly with the length of the sole and consequently also varies the height of the heel.
Let’s see the example in the figure: if we want a 7 cm heel, the actual size will be in sizes 37 and 38 but will increase or decrease by 2.5 mm every two numbers (39/40, 41/42, 36/35 or 34).
So if you want to buy a shoe number 41 and you want an 8 CM heel we suggest you to select on the site the heel height 7, because if you choose the heel height 8 you will receive a shoe with a heel almost 9 cm, also measuring the heel and insole
