        As most freediving fins size is for using with socks. I am Euro 42 ordered Euro 42-43 fits perfect with 3mm socks and even my 5mm winter socks.

          They fit well barefoot, but using 3mm socks is a little tight. I was worried about chaffing during long snorkeling days but they do not chaff. Great buy!

          nick p  how do they compare with the razor pro in terms of stiffness / weight / length ? cant find this info anywhere , thank you!
          SEVEN K  I guess it's pretty stiff. Sometimes i feel sick my ankle. Weight and length is almost same with razor pro. I recommend soft blade like carbon or fiber glass.
          Katie D  I am a women's shoe size 6.5...would the smallest size the 38 be too large in these? I would prefer to not wear socks as I dive in warm water. Thanks!
