your butt was not made in a factory , so the factories that actually make bike saddles
have to make a thousand + different ones, to try to offer something to work with your anatomy.
At least a leather saddle, be it Berthoud*, Brooks selle anatomica or who ever ,
has its natural tendency because of the century + old things, to break in like a pair of leather shoes, over time..
