These boots are made of seal skins with the hair removed. The soles are crimped at the front and back to follow the shape of the foot. Loops made from skin attached to the top part of the soles to hold laces that would have wrapped around the boot. The cuffs at the top of each boot are separate pieces sewn on with a sewing machine. Running inside the cuffs is cotton cord for tightening the tops of the boots.
