I may try some of those wool defeet blaze socks. I want to address some of the recent comments:
Ranger, you say that in the winter you ditch the road bike for your mountain bike. That is all fine and dandy but completely defeats the purpose of me riding. I am riding outside because I do not want to do long endurance rides on a trainer/rollers. I do not feel comfortable doing endurance rides on a MTB and furthermore I do not own one so the investment of a MTB would be way too costly and probably not cost-beneficial to the type of training I am looking to acheive. You also mention boots. I understand that work boots will keep my feet warm but at the same time, they will also mean that I have to go back to platform pedals. If I have to do this, I will, but I would prefer to try to keep my bike outfitted as closely to how I plan to use it come race time in the spring. I do not plan on doing very many of my hard workouts on the road, but rather on rollers or a trainer. As I mentioned before, the road will be used for those long endurance rides of 30-50 miles. Also, you mention the weather in your area in KS...I am in NE Missouri and it is already much colder here, not to mention the iowa winds that we are known for.
As far as my road shoes are concerned, I have enough room to be able to have one poly sock and a wool sock and they still are not tight on my feet. I may have to try the sock and baggie idea next time I go out along with using some duct tape to tape up all the holes in the sole of my foot as well.
Keep the suggestions coming!
