text: don't be wearing thick cotton athletic socks if that is what you have! They absorb sweat, then they start to chafe...and pretty soon you are either blistered or rubbed raw.\n\nGo to your running store and buy thin socks (short on the ankle, usually some design or something on em, and about $6 or $7 a pair) and wear those.\n\nCheck out this site, it shows the type of sock I am talking about...these are a little more expensive than I like, but they are exactly the size and material:\n\nhttp://www.swimoutlet.com/Triathlong_Socks_s/540.htm\n\nRe the blister...take it easy till it goes down. Sometimes if they are small i pop them and wrap them...but bigger ones just need time...
