I ride 100 miles a week on my UNPADDED Brooks leather saddle with no pain or numbness. The one time I rode a heavily padded saddle (on a borrowed bike) I was in agony after an hour and completely numb after two hours. It was awful!!!
Sometimes if you wear chamois that are too thick you can get numb too. Too much padding can be very painful especially on longer rides.

I think some women's saddles are designed by men with the idea that women just ride to the corner store and back on "comfort bikes" and want to feel like they are riding on a pillow. For myself, I have found that pillows hurt.

Hopefully you can go back to the more painless saddle you had before?
