The lower leg (and especially the foot) have a pretty fancy pattern of skin innervation by the terminal branches. For example, the skin of the foot is innervated by 7 separate nerves:

1. Superficial peroneal nerve
2. Deep peroneal nerve
3. Sural nerve
4. Saphenous nerve
5. Calcaneal branch of the tibial nerve
6. Medial branch of plantar nerve
7. Lateral branch of plantar nerve

Also good to keep in mind that the anterior compartment is innervated by the deep peroneal nerve, the lateral compartment by the superficial peroneal nerve and the posterior compartment by the tibial nerve.
