I have a question about preparing your feet for OCS. Several people have told me to soak my feet in rubbing alcohol every day prior to OCS. They say it drys out your feet and toughens them up, which may help with blisters. Has anyone else heard of this? Does it work? The other thing I heard was bring a small thing of vasoline and moleskin with and put it your on feet before a hump. I am just looking for ways to take good care of my feet. Any ideas or suggestions?
