The Falke socks I ordered because I love to run in the summer with invisible socks. So far I have resorted to on socks Decathlon back, which are very thin and with a special socket design (strong elastic waistband, rear cut slightly higher). The Hawk I ordered, because they looked from the style quite similar and the Decathlon socks in only one color available - unfortunately you see the socks in your shoes because of the color significantly. The Falke socks are well-made, sit prima (the size is exactly right) and slip and do not migrate when running. Unlike the Decathlon Socks (sitting with me as well!) Are the hawk but very thick and the feet after running significantly wetter and warmer than in the thin Decathlon copies. For the summer, actually too warm and too short in winter. For the damping of the shoe and the sock is not responsible for me. As the falcon are also a good deal more expensive, but I'll probably stick with the Decathlon socks again and accept the strong turquoise.
Update: The Nike Elite Hyper-Lite no-show have now proven to be a very good alternative. Very breathable, thin and significantly better than the falcon for the summer. I have also for under 7, - Euro get.
