In a merino wool and cotton rich fibre blend, the special structure of these kid’s UphillSport Hiking Socks with a layered cotton body and wool added to an extra-thick terry pile cushioned sole makes them ideal for wearing with walking boots.The thermally effective fabric blend will help keep cold out, but won\'t keep damp air in either. The breathable ventilation structures of the weave promote dry feet and a comfortable temperature. Made in Finland, UphillSport Hiking Socks have hand linked toes for smooth seams, a fitted heel and elastic grip at the mid-foot, supporting the arch and keeping the socks in place. The tops and half calf length legs have a secure 3x1 ribbed shaft. UphillSport use only mulesing free merino wool.
