very good functional sock. They fit perfectly, one does not feel the seams and it is not too tight. But this is always one's own feelings. Otherwise, the sock has completed an immediate hardship test. I had to hike with and accordingly they had to endure a lot. Bulgaria mountains, tours over 8-10 hours, heat, cold, everything was perfect. As a function sock absolutely suitable. Wicking almost perfectly. Price performance absolutely great ... Who's sports and also more extreme move., .. Buy buy buy ...
