The energy used in walking causes the feet to become hot and hence the phrase gets its current meaning, which is to wait.
The origination of the phrase comes from the 1500's where cooling the heels of horses was a common phenomenon in long travels. The earliest literary use came from the year 1576 but back then it was 'cooling the feet' rather than heels.
The speculation is that the feet have been replaced by the word heels over the centuries that the phrase has been used.
