Consider the foot as an example. Shift the attention to the front half of one foot. Thoroughly examine all the sensations in that part of the foot without losing awareness of the breath. Investigate the foot sensations to see if any of them change with the in- or the out-breath. (When you first start, you will probably not notice any changes.) Repeat this with the back half of the same foot. Then, move to the calf and lower leg, again examining all the sensations while looking for any specifically connected to the breath. Repeat this for the other foot and leg.
