Hope my experience can help. I owned 3 pairs meermin which they are Olfe 8.5, Hiro 8.0 and 8.5.Olfe feels snug to me and took abt ten time wear to breakin. Hiro at 8.5 is comfortable and has some room in lenghtwise so my second purchase of hiro was half size down. I found it snugs but i took severval time to break in only. Hiro 8.0 did fit my feet very well.
