CHRISTINE C Sorry, I returned the pants and can't remember if they had side zippers at the bottom of each leg. I vaguely recall that they do, but I could have misremembered. Note that the main reasons why I returned the pants are (1) the size was too big for me (I can't remember if I bought M or L, but TNF women's M usually is the right size for me) and (2) the pants were irritatingly/embarrasingly too noisy when just even walking around in the house in them.
