Without the right footwear you are inevitably going to get blisters where your feet rub against your shoes or boots. But conditioning your feet is crucial apparently when looking at how to prevent blisters. There are a number of ways of doing this apparently from what I glean from other folk (primarily those who've already completed the Oxfam Trailtrekker) and from reading whatever I can on that there Internet.
It's all about hardening the feet (to a point). Firstly go barefoot at every opportunity and walk as much as you can barefoot (not suggesting you go do your shopping resembling Jesus but I'm sure you get my drift) this dries out the feet and hardens them naturally making helping prevent blisters from forming when walking.
I'm not sure how much of an urban myth this one is as it wasn't tried and tested but came from a reliable source. Dab Friars Balsam onto a cotton wool ball and rub this onto your feet and let it dry, this again helps dry out your feet and helps prevent blisters forming.
As much as it might appear a good idea and a pleasant experience at the time a pedicure before any long distance walk is a bad idea and is not how to prevent blisters. It softens the skin of the feet and makes the pressure points far more susceptible to blistering.
After reading the above it would appear that I'm out for drying my feet to a crisp and hardening the skin on them until you could use them as the foundations of your next building project. Yeah this isn't the plan and there is a limit. If you go too far calluses end up being below the surface of the skin and can cause irritation when walking so the idea is to attempt to dry out your feet but by being sensible. Hopefully by looking after your feet in this regard may be a further way in how to prevent blisters, I'm hoping.
