Difference between "foot" and "leg" in spoken Japanese


After going on a long run, if you want to say, "My feet are sore", I would
imagine that in Japanese you would say 「足が痛い」. If you want to say, "My legs
are sore", I imagine that would be 「脚が痛い」.

How do you disambiguate one from the other in spoken Japanese, while
minimizing additional explanation or without having to explain which kanji you
mean?
