Right now I use seac f100 pro fins size 36-37 and they fit perfectly but i consider to upgrade my fins into long fins. im thinking to choose MOTUS long fins, but im still confused with the size. i am a very tiny man and using woman shoes size 37.5 (US=6.5), my sole size is approx. 23-23.5 cm. Does the smallest size of SEAC motus (36/38) fit in me? Thank you.
