Lovely looking shoe but I disagree with website advice to size down. I am usually size 38 - 38.5. I bought a 38 and they are very tight. I am hoping they will stretch. If I buy another pair I will probably size up.
Ordered a blue and a black version. Towels felt quite hard and "crispy" so I washed on a delicate cycle as they are advertised as getting softer with washing. The black towel has shrunk to about half the size of the blue one. The blue one has probably shrunk a bit too although it's difficult to tell.
