First, what is a saddle sore? Well, there are two types: One is chafing-related saddle sores, which develop from the repeated rubbing of the skin against the chamois in your cycling shorts. Two, you get spots or boils which are actually bacterial skin infections that develop from concentrated pressure and related reduced circulation. While you should invest in good cycling shorts with good padding technology, you must address the root cause of the problem. Eliminate micro-sliding on the saddle, which causes chafing, and enlarge the contact area with the saddle to eliminate concentrated pressure on your butt.
