Gail,
I have some suede LaCanadiennes and there is a slight bit of bunching at the ankle but they don’t have the elasticize back. On the other hand, the suede does not wrinkle. They have a tidy appearance, though they seem to be a little worn now after two years of heavy use.
I’m curious to know why you went with the brown suede if you wanted black. Is it because you think they will wrinkle less?
