The Merino Boot sock has a full loop-pile construction throughout giving the sock a uniform feel and weight around the foot and the leg. The loop pile, whilst still dense and durable, has a little bit more loft to it giving the feeling that the feet are floating on air. A chunky, non-restrictive welt, fine toe seam and specially designed grip sections only add to the all-over comfort, whilst the Lycra content maintains a sure fit wash after wash.
