Have to go hiking / mountaineering (usually with crampons sturdy shoes on the way) for a long time the gängigenn Falke - worn TK 1/2 socks that have also proven. Ultimately you get here but for much lower price - or the same price but 2 pairs of socks :) roughly the same offer. Apart from the composition - along with similar poly ...- synthetic fiber blend used in the new Hawk socks even merino wool is used instead of cotton as used herein - take the socks namely not much. .. That the socks have a special cooling effect or similar I could not tell - but are superior in this area probably thicker (Merino) mountain woolen socks - dry they are also rel. quickly. The Coolmax sock is very comfortable, I had been bladder (some multi-day tours) none - the higher elastane content I find very pleasant, because you do not like pure wool socks or wool socks with very little synthetic fiber fraction and the current sizes (43-46 etc.anstatt individual sizes which then really fit) by some walking begins to swim in socks - The fact that merino socks are sweaty ascent to not really odorless and also after 10 or more "gentle" laundering programs are slowly but surely becoming less speak in my opinion in addition to the huge difference in price for eg precisely these socks. Abstract: Top, good properties undecided in heavier shoes, whether cool or was not - but overall really good :)
