Love my Swiftwick "Pursuit" socks. Very comfortable. I did not realize when I ordered that they are not the say "model" as my other ones which are the "Aspire" I believe. Love the Aspire too as they are a bit thinner without the cushion and the merino wool are softer than the polyester?. The Pursuit are thin on top but have a little cushion on the bottom that just barely comes up the heel and over the toes. Makes my shoes a little snugger but, so far I have not needed to use my silicone toe caps with these socks. (my second toe is longest and both have chronic "runners toe" (weird toenail, callous, etc).
