Ice climbers don't have as many options as rock climbers. When an ice climber is on a frozen waterfall, there are only a few things that she can do to use her feet. She can frontpoint (the German technique), she can use the American technique or she can use the French technique.
Following is a simple breakdown of these techniques as they pertain to ice climbing.
In mountaineering, we try to avoid frontpointing as much as possible. This is because it wears out the calves quickly. In waterfall ice climbing, it is incredibly difficult to avoid this technique. Indeed, most of the climbing that one will do on steep and vertical ice will require frontpointing.

Proper frontpointing requires that not only the front two spikes are engaged, but that the second set of teeth are also engaged. To do this, a climber must drop her heels. This allows the secondary spikes to bite into the ice.

Ice climbing requires a tremendous amount of calf strength. One of the best things that you can do to prepare for an ice trip is to train your calf muscles for extended periods of use. You could also do your best to limit the amount of time you spend on your frontpoints...
The American Technique is a great way to rest your calves while ice climbing. It is quite common for people to get fixated on frontpointing and not to take rests. The American technique allows for rests.
This technique, also referred to as Pied Troisieme, requires one foot to be placed with the frontpoints engaged while the other food is flat in a French position. French technique is essentially a technique wherein the spikes on the bottom of the crampons are fully engaged on the ice.
Fully engaged crampons do not work the legs anywhere near as hard as techniques that require frontpoints to be engaged. As stated above, French technique is a way to avoid overuse of your calves.
The simplest way to explain French Technique is that the feet stay flat. All points are in the ice. If you can do this on steepish terrain, then this will really allow you to rest. Indeed, areas where you can employ this technique are also some of the best for placing ice screws. Never ignore an opportunity to rest if it allows you to get gear, this can be scarce on ice climbs sometimes...
A few months ago, we did an entire article on French Technique and the use of the Cross-Over Step. To read that article, click here.
Whenever you ice climb, think about your feet. But don't just think about them as cold lumps that might help you through the climb, but instead as a dynamic part of your body. If you always think of them as dynamic, it is far more likely that you will be able to use them in an effective way.
