FINIS Shooter Monofin Swim Fins

I got this to go inside of a swimmable mermaid tail. I am more used to a different type of mono fin, so it was interesting to get used to this one which is quite rigid and short, but the product itself is well-made and got to me much faster than I expected which was great. It did come with some kind of strange Tacky powder on the foot pockets, which I assume was just to protect it or something. It did leave some weird residue on my feet which washed off easily in the shower. I also am a size 7 shoe and it feels initially like the foot pockets fit well, but in the water they stretch a bit so I would recommend getting thin socks to help with any rubbing and or gapping.
