My butt is a limiting factor in how long I can ride. I tried a number of different saddles before I found one my butt liked. Good saddles can be expensive and there's no guarantee that you can just go out and buy comfort. You will need to spend some time in the saddle conditioning your tissue. That's inescapable. There are ways to avoid throwing money on top of money at a problem. Some shops have a bin of take-off saddles they will let you try or buy cheap. Certain manufacturers have a demo program. ISM is one of them. You pay a fee to rent a saddle for a week. If you want it, your fee goes toward the purchase price. You can also try another one before you decide. That's how I arrived at the ISM Adamo Typhoon that allowed me to ride my first century.
