Leather most certainly will stretch until it breaks, given enough pressure and/or improper care.
Also, leather or synthetic in a SADDLE will not stretch, except maybe leather stirrup fenders/straps. Synthetics do not stretch at all.
There is no part of a saddle that is going to "stretch" except for replaceable pieces like the stirrup fenders/leathers or billets/latigos. Synthetic nylon latigos/billets don't stretch much at all, and only break with a LOT of use/wear. They generally last longer than leather latigos/billets, which can stretch out of shape, crack, and break with use and even just time.
