Kyrgies Molded All Naturals, a house shoe designed for those wanting a firmer slipper. - Handcrafted using natural moisture-wicking wool felt and chemical-free natural materials - Thick vegetable-tanned leather sole specially molded to give support, non-slip grip, and additional felt cushioning. - Warm and cozy Note: Kyrgies describes these as navy (now sold out) but they are more of a dark cobalt or teal. Bought these for my husband last Christmas. He wears a size 11 and they were too small—they’re probably best for someone who wears a men’s 10/10.5. We immediately replaced them with a larger size and he has never worn these.
