Highly recommended product!
I learned of Ruby's Lube while roaming the booths at the Coeur d'Alene Iron Man event.  I have struggled my entire life with blisters when walking or jogging any sort of distance.  I was about to dismiss the product because I assumed it would just soak into my socks before having a chance to provide any benefit.  In the end, I received a free sample and decided to give it a try.  I'm so glad I did!  Even with socks on Ruby's Lube has worked like a champ during 5-6 mile jogs and walks.  I haven't had a chance to try it on a much longer hike yet but I have high hopes!  I've also used Ruby's Lube with suede high heels and sandals and I really couldn't believe how good my feet felt during and after wearing them.  Ruby's Lube didn't leave any stains behind either.
