[pct-l] Simple idea to prevent blister

[Yoshihiro Murakami]

The cause of blister is shear force to exfoliate the dermis and the
epidermis  by the friction. In other words,  it is necessary to reduce
the friction between skin and socks to prevent blisters. There are
several strategies.

The smart wool socks reduce the humidity of the surface of skin.
The socks should be changed regularly.
The tight socks reduce the friction of skin and socks.
Use loose footwear. The friction occurs between socks and footwear.
Cover the skin with the film of the small coefficient of friction.
Use the insoles which has  ventilation effect.

I made many ventilation holes in new insoles. It is not a new idea,
but they are new insoles. They works well..
