One way to fix it is to put the foot in boiling water (right out of the kettle) for 10 seconds and then squeeze the joint as tight as you can (not with your nail of course). While you are squeezing it, put it under cold water for about 5 seconds and the joint should be tighter now.
This is of course just a temporary fix as the rubbery nature of the plastic will cause it to soften up again during the warmer days.
