Available in a medium/narrow fit (model 1015090) and made in Germany, the slippers are praised for comfort but the shearling lining may mat with heavy daily use.","url":"https://www.simons.ca/en/men-footwear/slippers/zermatt-mule-slippers-men--16708-21305?colourId=0","brand":"Birkenstock","condition":"new","product_category":"men footwear > slippers","material":"Upper: 70% wool felt, 30% polyester;
