I have some short fins that I use for lap swimming which are designed to work your leg/thigh muscles more. They are called Zoomers and I got them on Amazon.com.
I love them, but I don't know if I am burning any more calories or not. They certainly make the workout more challenging
The way that swimming is recorded on this site seems so wildly inaccurate anyhow (just minutes, not speed or rate) that I'm not worried about calorie measurement too much anyhow. I swim my 1.5 miles and call it good.
