Material
These sheep wool slippers from Yoko Wool are made of wolborg. Wolborg is wool knitted into jersey. Irish sheep wool is used for this.
The big advantage of slippers, made of natural materials such as sheepskin, is that your child gets wonderfully warm feet. Sheep's wool is moisture-regulating and breathable and has the natural property that it can absorb up to 30% of its own weight in moisture without feeling wet or clammy. Woolborg slippers can be worn barefoot.
