Not if you buy them separately. I think on their site they have a full size and half size package that can be ordered together for a discounted price. I didnt do that originally because I wasnt sure how they would be, so I ordered 1 full size first fit to my Crispis and then reordered a half for all my daily work shoes.
Wore mine for another 2 miles last night and they seemed to take up all the space and give me more support where I was getting hot spots in with the standard insole on the Crispi.
