The shoes are excellent for the reason I bought them, which is for the beach and pool, but there is a problem with the sizes, meaning that even though my size is 40, in these shoes the 39-40 is big and the 38-39 is small

It is incredibly comfortable - the sole is soft and absorbs shocks. However, the sizes generally available in this code are not practical. In sports I am 41 - sometimes even 40.5. This model is 39-40 or 41-42. Neither of the two suits me - so in the 41-42 that I got, there is minimal space in front of the toes and I have put a special cushion in front and I am fine! I definitely want the other colors as it is perfect for the office!
