Hm. Maybe that is the case. Ordered the 40-41 version also, just in case. And other fellow freedivers confirmed that sometimes those sizes differ, and that it is best to try them on. Problem is, they are really niche products, and most dive shops around here don't stock much freediving fins and just order as required, so a bit of a hen-and-egg issue there...
