I have blisters on the sides of my feet,heel and toes! i had some loafers that seemed comfertable but wernt. now i have to work 12 hour shifts at the mall on friday and i think if i keep going in these shoes i will have to go to the ER! no joke. I have a heel spur and plantar facitis so i can already feel my tendon tearing. what can i do? help me asap!

btw no sneakers or open toes
