I have a pair of Nudie Slim Jim dry, size 30 waist. They were a bit tight when I first got them but now, after five wears, they fit perfectly. If I were to get a pair of Bootcut Ola, would size 30 fit? I think the rise is different so I'm not sure if I have to size up or down or not. Also, anyone know of an online retailer that might have bootcut olas in stock and that ships to Canada? I've checked a few so far and can't find my size.
