Indoor shoe with lacing. Can also be used outdoor. Has heel. Made from cowhide with a nonslip rubber-sole. The shoes are crafted in Swedish Lapland above the Arctic Circle in Sattajärvi shoemaking. Kero specialty is the naturally tanned hide which means that the skin is tanned with only natural substances. This method is known since time immemorial and by far the most environmental friendly. Tanning agents from bark are added to the process, and the leather also takes on the moisture-absorbent properties of the bark.
