I have officially written off "cheapo" impulse buy shoes... I can't do it anymore with this belly!
I have a growing collection of clarks, birkenstocks, and one pair of earth sandals and am hoping to get a pair of Dansko's that i've had my eye on before school starts. Even just everyday around the house and running errands I can't do the cheapo no support shoes anymore... my back is KILLING me, but lukily I have a great rice bag that I can throw in the microwave and ease some of the pain. So I can't imagine how i'm going to make it through the day once school starts!
Re: purging of the shoes...
I am a teacher, too, and know it will be a killer (especially by November/December!) I just bought a pair of really cute Naturalizer flats that don't look like "comfort" shoes at all but are like walking on air. Good luck staying comfy in the classroom.
