Be aware of where you're walking. Don't stomp blindly along the trail, but be attentive to each footfall. Try not to step on small trees, sprouts or even bugs; walk gently. Before the age of sneakers and hiking boots, hunters used to walk toe to heel, not heel to toe. Try this, as it creates a much more delicate gait, and requires attention to each stride. It's also interesting to walk barefoot for a ways, as this helps increase awareness of every step.
