I soak for about 20 minutes in a trashcan that fits both my feet and goes to about half way up my calves. 5lbs of ice and fill with water.

I do it before work and then after. I dont go anywhere til i soak now.
i also have large ice packs under each thigh that i sit on in the office. I have a second pair i rotate out of the freezer. A second 2 sets are at home. I call ice my 'morphine'.
