I've found that while blisters may not be totally eliminated by the use of moisture wicking socks they definitely decrease the frequency and rate.

I wanted to wish you good luck at the Avon 3 day.

Thanks for your order of trail maps. They will be sent shortly. Was a great success last year. Wow Julia, your website knocked me out. Of course you can link to mine, and I'd like to link to yours as well if you don't mind.
