I don't know... most paddle style fins work on the basis that they flex some (or alot) in order to push water backwards... my Dacor DXD fins use the same type of flex to work well... however, whereas mine flex and use the flexibility of the plastic and rubber, these are a little more mechanical, and adjustable...
