I have been having trouble with using my Macro lens and getting photos in focus. I will attach a couple of photos. I am using a tripod and I am manually focusing. However, my tripod is not the best in the world. It is my husband's that he uses for his video camera. Any suggestions? Maybe just lots more practice? Thanks for any help!

Why are you using a macro lens on such large subjects? If you are manually focusing your camera you should see what is in focus and what is not. If you want a better photo I think you should use a different lens if you are using a DSLR if not just don't choose macro for close ups.
There is really absolutely nothing wrong with using a macro lens for other than macro photography. A macro lens has the exact same depth of field (DOF = the distance between the closest point of acceptable focus and the furthest point of acceptable focus) as any other lens of the same focal length which is being used at the same f/stop and same distance focused on.
In other words, if I were using a Canon 100mm f/2.8 macro lens on my Canon 1.6x crop camera (all Canon DSLR cameras except for the 1D-series and 5D-series are 1.6x crop cameras)and I was focused at 10 feet and using an f/4 aperture; the depth of field would be .45 feet; or .22 feet in front of the point focused on and .23 feet behind the point focused on. If I were using my 70-200mm f/4L IS lens at 100mm, focused at 10 feet using f/4; my depth of field would be exactly the same....
I suspect that you were shooting at a wide aperture (small f/number) and that the camera selected the point of focus for you, which was at the far end of the rock. Your depth of field was quite narrow and did not include the front of the rock or the shoe.
The way to remedy this would be to use a smaller f/stop (higher f/number) and or shoot from a further distance. of course, using a smaller f/stop would decrease the amount of light falling on your sensor and your shutter speed would have to be longer and/or you could use a flash.
The way to tell the difference between a picture which is fuzzy because of incorrect focus and a picture which is fuzzy because the shutter speed was too slow and the camera moved during the exposure; is that when the focus is off, there is usually a portion of the image which is relatively sharp (in the case of the boot picture, it is the back end of the rock) and when the picture is fuzzy due to camera movement, no area of the image is sharp.
When you have an out of focus image; it can be operator error; in that the focus point was incorrectly chosen or the f/stop was to wide (or both). However, it can also be equipment error in that either the lens or the camera (or both) is malfunctioning.
