I want to order these shoes, but they don't do my size 8 but they do them in a size 7. Is there a way I can stretch the size 7 to a size 8 so they'll fit me?

Unlikely... part from anything else, if you try and stretch them, the stitching is likely to split, plus you won't stretch them enough for them to be comfortable..... AND, they will bulge in odd places... don't do it.

they will stretch once you wear them a bit
