Hey UW_IKARUS!
Your post is really helpfull but one thing just confused me. You write you have a foot size 41 (the same as me), but you write that your monofin is size "S". On
LeaderFins.com they write that "S" size equals foot size 36 (???)
What size monofin do you have?! And should I get a "L" = 40-42?!
Eager to hear the answer, since this is the last doubt about size I have.... :-)
Best regards,
Toni
