Shenandoah National Park. I have run here numerous times and really enjoy the long climbs and mix of rocky trails and old forest roads. The week before I ordered a pair of Drymax Max Protection socks from Running Warehouse. Drymax has a 100% satisfaction guarantee. I have been wearing there standard running socks for a year now and love them. This lead me down the path of spending $25 for a single pair of socks. If I was not satisfied I would contact Drymax and take them up on their offer.
Location: Shenandoah National Park
Weather: 80+ degrees down low and raining off and on all day
Time/Distance: I covered around 38 miles / 9000 feet of ascent and descent. I was away from my truck for a total of 11 hours including refilling water out of streams, talking to people, changing socks, and taking pictures. (Think enjoyable day, not race pace)
Details: My feet were wet all day and the socks worked wonderfully. Around 20 miles in I started to feel a little pain behind my second toe and on my one heal. This is a very normal place for me to get blisters. I ran down 2000+ feet of rocks and sat down to change into a standard pair of dry drymax socks I had in my pack. My feet looked like they had been soaking in water for 2 days, but no visible blisters or damage. The new socks felt great for an hour but then the pain started to come back. I stopped one more time before a 7 mile descent down some very runnable fire roads. I was going to put some body glide on my feet to see if this would help prevent any additional damage. I ended up taking off the standard socks and putting back on the wet and dirty max protection socks. I ran out and the pain did not get worse. The next day once my feet were dry I had very minor hot spots that did not bother me at all. Much, Much better than I would have expected with wet feet all day. I believe if I had a second pair of max protection socks I would have been even better off.
Recommendation: I cannot speak of their durability or long term usage. What I can say is that if I need a goto sock for long distance this is my sock. I highly recommend them to anyone with blister issues. Do not bother spending your hard earned money on them for every day use or the mid week run, but when the big and wet miles are calling break them out. You will not be sorry!
