I suffered with blisters and stinky feet for years until I put coconut oil on the total foot before putting on a poly sock with merino socks over.For setting on the stand after a few miles hike in: Toe warmers that glue onto the toes.Costco sells enough to last a 10 day season for 5 or 6 guys for $15.Hand warmers are a great item for the same price.The toe warmers are designed to work in low oxygen so don't try to use them for hand warmers as you will likely be burned and hand warmers wont work in your boots.I can't over stess enough of how good that coconut oil works to prevent blisters and hot spots.I tried Sport Knit and Moleskin to no avail but remembered the old farmers putting rendered bearfat on their feet where I lived up in Ontario,Canada.Bear fat isnt easy to find so researching lead me to try organic coconut oil.It worked and much easier to find . It's antifungus-bacterial too.
