+ 1 on the Selle San Marco Aspide Glamour. I have one on each of my bikes and have not had a sore spot anywhere since I started using this saddle.
That said, I think you were going with some padding to stop the back -> hip -> down the leg pain on your left side? I actually have that same pain as well I have a permanent back issue resulting from falling down stairs 3 years ago, and riding the bike sometimes aggravates it and causes spasms. I also have a shorter left leg and I have cleat shims.
I use stretching, icing and my chiropractor to deal with my back pain. I use my Aspide Glamour to prevent any other kind of soft tissue pain.
