Oh, I really like this style CLBA, thanks for the link and welcome to the forum :happy::happy::happy::happy::happy:
I agree with Louise that they are true to size unless wide fit in which case they will slip off. I wouldn't go for a size down because the sole would be smaller/shorter than my real size. I feel that lengthwise they are true to size.
Thank you Marina!- yes i thought they were nice for a change ! x
