If a saddle doesn't fit you from the git-go, it never will. Leather, plastic, carbon, whatever. A leather saddle's fit may improve with age, but if it's not good to start out, try something else. Over the (35) years, I've found exactly 3 saddles that fit me well: Brooks B17, Unicanitor 55 (the plain nylon unpadded one), and one particular Brooks Pro. I've got 2 (old but sound) B17s and 3 Unicanitors on bikes or stashed away. That should be enough to get me thru the next couple decades.
