I bought a couple pairs of Injinji tetrasok's ("toe socks"), and ordered these through the mail to get the "performance" series, the ones made with Coolmax. My thought was to use these as my liner socks to reduce or eliminate toe blisters.
According to the package these are 70% Coolmax, 25% Nylon, and 5% Lycra.
The package says to machine wash warm and line dry, so I just did a low spin cycle and then hung them up on a hanger in my bathtub last night.
Eight hours later these are still quite wet. Were these normal liner socks, they would be close to if not completely dry by now. This suprised me, but sort of matches my initial feel of the socks, that they didn't feel as dry on my feet as I had expected, though I'm not really sure of that (yet).
The packaging for the socks talks about "a CooMax moisture wicking lining and a resistant nylon outer shell built with Lycra fibers".
In the FAQ on www.coolmax.invista.com there's this text:
"Energy Saving Tip! > Because Coolmax® is so quick drying, you really don't need to use your dryer. If you've got clothes made from 100% Coolmax®, just hang 'em up to dry and be amazed at how quick it happens! Great tip for travel too!"
Well, I was amazed alright, but not in the way they suggest.
Any ideas of what's going on here? Is the particular sock material blend that Injinji used defeating the general purpose use of CoolMax, or ... ?
Further muddying the waters, I see on the CoolMax website that there are three types of CoolMax: "Everyday", "Active", and "Extreme". No where I can find either on the packaging or www.injinji.com which of those is used; I've seen that elsewhere too (including on this site) --- sometimes a product will specify which type of CoolMax is used, others it just generically says that it's CoolMax and leaves it at that.
Liner socks that are quite wet after hanging for eight hours in a dry room aren't something I care to take along on an extended backpacking trip. I'll test these further to see how well they dry out when I'm walking in them, but I would appreciate any insights on this from others.
