If you've never tried these, you'll be delighted! However, they are intended for those who prefer to go barefoot. If you prefer to use foam or other arch support, this may not be the right fit for you. It's like having a winterized version of your own foot. There is no cold sweat like with slippers made of synthetic material. Wool absorbs moisture and stays dry even under heavy use. They are amazingly comfortable and lightweight. I recently washed mine for the first time (after 8 months of wearing) because I had a small wet/sticky stain on the inside. The stain is gone and they are like new. It took about 48 hours to fully dry since it's winter now. I have a pair that I wear all day at work at home with leather soles and a pair that I wear outside with rubber soles. I can't say enough good things about these slippers/shoes!
