Thank you everyone! I don't know if anyone else experienced this with their Pradas but mine were SO uncomfortable. The area right over my arch KILLED my feet within minutes. They were virtually unwearable. I've never had an issue with my arch before so I'm not sure what the deal was here. I took them in to have them stretched and the guy told me it wouldn't work. He was right. It didn't. So I was fortunate enough to meet someone who's been a shoe repairman for 30 years. He told me it was no problem at all. He gently stretched them over a period of a week and WOW...yeah...they are like slippers now! One more Zam issue solved!
