footwear solutions for the hot & humid days

La
To all of my fellow July Mommas, depending on where you live, how are you dealing with the heat and your swollen feet/ankles? I know that it's only February, but NJ is already having days in the 60's and 70's! The high school that I work in is not air conditioned and the heat/humidity is killing my feet! Other than flip-flops (which provide zero arch support) what are your footwear solutions?
