Duckfeet are the classic ocean lifeguard fin, they all have a pair somewhere. Big, heavy, crazy stiff, and capable of providing major thrust when you need it. I’ve had my Duckfeet for quite a while and really like them. They’re not perfect for most things I do but they’re pretty ok at just about everything. I’ve bodyboarded and body surfed with them, and they’ve been used to pace swim in the Catalina Channel for Chris D, Cliff C. and Evan M. My duckfeet are a permanent fixture in the back of my truck ready to go anytime I need them.
Duckfeet start out pretty tight and rough on the feet. As a matter of fact your feet won’t like these at all when you first take them out. Stick with it though. After a while they’ll stretch out a bit and become a lot more comfortable. I ended up buying some neoprene fin pads for the heel strap just to make sure it stayed that way.
If you need an all around ocean swim fin this is a solid choice. If you’re looking for a pool fin, this ain’t it. If you’re serious about using fins for surfing these are ok but you’re better off buying something more surf specific like Churchills, Lagunas, or Vipers.
Duck Feet are pretty easily available at sporting good shops, I got mine at Big5, or you can buy them online here.
