Molchanovs Silicone Bi-Fins

Hello,

I did my first free diving course and loved it. I want to get into it more and want to pickup a good pair of fins. My instructor used these and they look super cool. I am a swimmer so used to using fins and personally don't like the super long typical free-diving fins at all (hated them during practice).

These are the ones:

They are pretty pricey so would love recommendations on other alternatives.
