What is the ruling on someone who performed ablution, then put on two socks below the ankles, and prayed in them?

The validity of wiping over the two socks requires them to cover the obligatory parts, including the two ankle bones. If a person performs ablution, then puts on the two socks, then prays, his prayer is valid. However, if he performs ablution, then puts on the aforementioned two socks, then wipes over them in another ablution, his prayer with this ablution is invalid due to the conditions for wiping not being met.
