...First check on what saddle works best for you (and yes, the only way to know is time in the saddle), but second, make sure your bike fits you. I used to have huge issues with soreness (though no open sores, thank goodness!) and found that on my old bike my top tube was too long, forcing my weight forward onto my hands. I was scooting forward on the nose of the saddle to compensate. OUCH!
