I ordered a couple of pairs to try. My impressions are:

• Drymax mens crew are ok to good. They're not just a tube, they have shape. They have a little bit of cushioning. However compared with my old model Thorlo they're significantly warmer.
• Wigwam airlite pro socks aren't so good. They're just a tube, they have no padding, and they're quite warm. If you have an incredibly tight shoe this might be ok.

I might have to try the new model Thorlo socks, even though the reviews all says they're not near as good as the old model.
