It's time for me to get a new pair of shoes. Being fairly new to Cross (but not to cycling) the question has raised itself many times in our club "are carbon soles better than nylon soles for cross?"
I've trawled the sites and forums and hope that someone can help me on this.
I guess Carbon gives you added stiffness in the pedal action but Nylon gives you more flexibility when running off the bike. Its gets fairly muddy here in the UK so toe spikes are a must as you clamber up the steep hills. So is it Sidi Spiders (nylon) or Sidi Eagle/Dragons (carbon)????.....
Since 10 days I am a proud owner of sidi dragons after having had the cheaper model for years. The dragon is really a step forward. The carbon sole is much stiffer when pedaling but running is no problem. One advantage are the more flexible spikes in the sole which are dampening the impact when running. Also the fitting is better. Maybe it is the heel support or they can be better tightened. Anyway the feeling is not so slippery when pedaling.
Jim, great to hear from you
My current shoes too are Shimanos with a fairly flexible sole, Q: why do the stiffer soles help when running when compared to the nylon??...Apologies for the second question, its just that Shoes can get rather expensive and would hate to get the decision wrong!
