All Wool We make our felted wool slippers the traditional way: by hand using only 100% New Zealand wool, soap and water to give them a light, cozy feel that makes anywhere you wear them feel like home. The more you wear them the more they mold to your feet to give you an individual fit that’s as personal as our time-honored manufacturing process signified by the red knots on the label that are hand-stitched by expert artisans. NWOT Runs small fits more like an 8.5
