Prepare a foot bath with two quarts of warm water and three tablespoons of Epsom salt. You can also use one tablespoon of table salt instead of Epsom salt if you don't have any. Take a load off and soak your feet for 15 minutes. You can also stretch your calf out to relieve some of the tension in your feet. Do some calf stretches for 10-15 minutes and you should feel some tension dissipate in your feet.
