I was going to suggest the size may be too large as well. A friend is having this issue and is switching to smaller shorts after some research. My dh finally decided that his "many" cycling shorts were all to big and is getting rid of them all. I have PI's and love them. They are the most popular shorts around here. I think you just need the right size, but it's possible a different brand may work better for you. I also have Specialized and love those too.
