Hi,
regarding peripheral circulation, I once met a guy who used chili pepper powder. This powder irritates the skin and provoques extra peripheral circulation. Anybody tried it ?
Wet feet being the main issue, I recommend a product called ephydrol. Containing camphre and formol, it stops excessive sweting and nasty odors,great stuff, especially when you travel like Dario and I, with only one pair of shoes.
saludos
