its even easier on sand, just use photoshops cloning or healing tool on the bottom cube face of finished pano
if you use ptgui, setting a low blend priority on the nadir image(s) can keep your feet from showing in the final pano too
for when i forget to stand to the cameras "wide" side

If for any reason Sam’s simple way doesn’t work (say an elaborate pattern under foot) then let’s make use of Alpha Channels
Set Photoshop WORKSPACE to DEFAULT VIEW
Drag and drop the image with your feet in it into the image space.
Locate LAYERS CHANNELS PATHS pane to right of screen
Click CHANNELS tab
Four thumbnails will appear R – G – B channels and sum of RGB
Locate beneath the pane the square within square symbol (CREATE NEW CHANNEL) and click it. A new channel thumbnail is created called ALPHA 1 and the other four thumbnails turn white and the image in the image space turns black.
Press CTR+4 (PAINT BUCKET) and drag into the black ‘image’ click it and the ‘image’ turns white.
Click empty box besides RGB thumbnail. Normal image returns.
Press B to activate BRUSH TOOL, make sure it has 100% hardness and paint out your feet and legs (which turn a transparent red).
Save as TIFF with new name if you wish and use this in the creation of your panorama instead of the original nadir image.
That’s it.
Ah, but there is a problem. If your feet were dead centre of the nadir, or at least if they were not overlapped by other images then instead of little feet you will get slightly bigger black holes. Well don’t complain to me. Tell Nike!
Better still – GROW LONGER ARMS!

PS When John Houghton explained this method to me it sounded very complicated but after one or too goes it become second nature.
This method works with CS and above. May not work with pre-CS Photoshops or Photoshop Elements. Perhaps someone could tell us which versions support Alpha Channels
PPS Here is a way to test if your Photoshop version supports Alpha channels. Drop this image into it. If Alpha is supported you should see my painted out feet in red.

Hi James
congratulation for the handheld technique; I saw no parralax error.
great surroundings and beautiful light/colors.
I almost always had major problems with stitching breaking waves when taking pictures on the beach. It probably requires a lot of processing.
I like what krpano did. it is a marvelous tool.
What I don't is the stitching errors.
Considering panoramas the closest image except "being there", there is no need in extra things left on the beach.
But there is always a chance to put it as art, using creatively the fantastic resources of flash.
regards,
Valentin

All the stitching errors are the result of parallax problems. The horizon is poor - neither level nor straight,amd wavy in places. If using PTGui, it's best to put control points only on the most distant parts of the scene, which are not affected by parallax. Use good lens parameters from a previous project. That will give you a good general alignment of the whole panorama, which can be levelled to give a nice straight and level horizon. The inevitable parallax errors on the nearby ground needs to be attended to in one way or another. You can use morphing, local transformations, offset nadir, cloning etc. to get things right, and yes - alpha channel masks to eliminate feet if desired. I don't like the projection chosen for the viewer, but that's a matter of individual preference.

Who cares about the parallax problems and mis-alignments.

Glad you got the Baywatch reference Doug 
I'll give the suggestions for parallax correction and feet removal a go, see if I can make it almost perfect.
I'm still pleased with the way it came out, HDR handheld and not too shabby.
John, what kind of projection would you like to see?
