[pct-l] Blisters 2-sock approach

[Yoshihiro Murakami]

The foot blisters are caused by the heat of the frictions between
socks and foot. So, It is important to reduce the friction. The ways
to avoid blisters are:

  1. to wear suitable boots or shoes.  I think slightly larger boots
lets heat go.
  2. to maintain appropriate moisture level. I usually change my socks
in 3 hours. Too dry and too moisture is bad.
  3.To use appropriate insoles. Good insoles prevents blisters and
injuries:I usually wear SOLBO:It is very cheap and effective.
  4.Antiperspirants  and drying powders  do not appear effective. I
found two papers in PubMed in this morning( I live in Japan )
  5. A thin polyester sock, combined with a thick wool or
polypropylene sock are effective to prevent blisters:  Knapik JJ, et
al. Sports Med. 1995 Sep;20(3):136-47."Friction blisters.
Pathophysiology, prevention and treatment." This layer system is
effective to exhaust moisture. I read this in other papers.

Thus,  Jereen 's approach is right. I had tried two socks approach
once but I gave up because of the shoes size. Now, I wear very cheap
smart sock and change new one when I feel moisture.

> Sean, I'm sure that you have had a lot of good advice in PCT-1 - and I haven't read all of the posts on the subject. I did a lot of Sierra backpacking during the 50's and 60's going up to about 15 or 25 miles`per day - - - not as far as some of the hikers do today. In those days I always wore leather boots - 6" high to protect my ankles and a size larger than my normal shoe size. Being leather, they required breaking in. What I and others did was to hike in a stream until they were thoroughly soaked and then hike them dry. The leather would tend to dry to the shape of your foot. Then you needed to oil them really well. We always wore 2 pairs`of socks. The first pair was lightweight slightly stretchy nylon that protected the foot from rubbing (and therefore blisters). The second pair was wool. I don't recall blisters being a problem when I used this approach. Today most hikers don't use leather but the 2-sock idea might help with todays' shoes. Has
