My best saddle is a Specialized Avatar. Though I've used it for quite some time, I don't find it particularly comfortable especially on my longer rides. (often I'll get a welt from friction in my perineal area) Besides, it is on the heavy side.
What makes for a more comfortable saddle? What factors should be considered, starting with my own sit bone geometry? How does one determine the best width, length, type of cushioning, style etc for themselves?
I know that it's often recommended that one try them out prior to purchasing, but I find it's not practicable to do so as usually a poor fit isn't fully revealed until many miles later.
This of course, aside from shorts padding and how I sit in the saddle
Any thoughts would be appreciated as I have a couple of long rides planned in the near future.
