I used to use a pair of Tevas. Change into them - cross - change back. One time we had about 5-6 crossings over about 3 miles or so, and the gi-normous amount of rain raised water levels to whitewater rapids level :-) Got through with the Tevas - and kept hiking in them until finished with the crossings, then changed back.

Now I have a pair of crocs for around camp - but I haven't used them yet for fording...
