While doing wudu in my office, it is not convenient to wash my feet with water. With washbasins only, it is quite difficult to lift your feet upto the basin in office wear, not to mention the wet floor left behind in the end as well, also, takes longer.
I know if you're wearing leather socks, you can wipe over them, as masah... can the same be applied to leather shoes, with cotton socks underneath?. Please note I would do a full ghusl/shower in the morning before putting the socks/shoes on.
JazakAllah. Rizwan
