I am pretty sure I have plantar faciitis-and it sucks. I used to wear regular tennis shoes to work until this past year. I had to have white shoes for school and at some point, I don't know when, it hit really badly. SO, mom bought me birkies with the cork insert. They were much better but then my heels were hurting horribly at clinicals. I was exceeding the amt of tylenol and motrin just to make it through clinicals (was really bad when I was just observing and standing in one spot). I ended up having to pad my birkies. So, on a whim I tried crocs. I thought I was in heaven. Instantly my heel pain went away and the calf pain subsided. Well, now my heels are slightly hurting again, my knees are horrible. I just don't know how to feel better. I do have hyperextended knees from a cheering mis=jump twelve years ago and I stand heavy on my heels so that doesn't help. I have new balance tennis shoes which hurt me. Any suggestions for good supportive cushiony tennis shoes?
