I bought the shoes for my three children. They are very beautiful and I am very satisfied with the shoes. We bought the shoes for the pebble beach on vacation - but they are super. To pool fitness I can not say anything. However, bathing shoes are very large. My sons have shoe size 29/30 and in the slippers Gr. 28/29 is still a thumb wide space. My daughter has Gr. 24 and in the slippers in Gr. 24/25 were two thumbs wide space!
