This is how to wipe over socks in wudu: put your wet fingers on the toes then pass them over the feet to the shin; the right foot should be wiped with the right hand and the left foot with the left hand. The fingers should be spread when wiping and it should not be repeated.

Wiping over socks is Sunnah whether they are made of linen, wool, cotton, camel hair or goat hair, whether leather is worn over them or not.

You can do wudu with socks on if the socks have been put on when you are in a state of purity and they are pure, and the wiping may be done within the time specified by Shari`ah.
