Smartwool Trekking Heavy Crew
The Smartwool Trekking heavy crew sock has heavy cushioning that provides extra insulation against the elements, shock absorption and support under heavy loads. Extra cushioning also protects the foot from the pressure of stiff boots and lacing, and an elasticised ankle brace holds the heel in place.
