This is my third pair. Really like these! Super comfortable and keeps my feet warm without over heating. I wear them just about everyday during the winter. The first layer on the heel did start to wear but the inner layer is thick enough that it wasn’t an issue. Mine never wore all the way through. They’re good for probably the fall/winter months and then may need to replace if worn all the time. But for the price, totally worth it. Just got my new pair delivered! I’ll continue to purchase. For me they’re my favorite winter sock/slippers!These are soft and warm. The grippers on the bottom are a nice safety addition, especially for those that have wooden floors.My teenage granddaughter loves them!as described and fit greatPerfect. My feet are warm.Socks are super soft and warm. Grippers on the bottom are substantial and you wont slip with these. I have 2 pair of thermal socks from this brand and love them. They keep your feet very warm and they are breathable so your feet wont get overheated. Good buy.Son muy cómodas y calientes muy lindasThese are perfect to wear around the house on cold days! When we lost power for days, they were a real blessing and we are 90 and get cold easy! Got two pair, one for each of us. He loves them as much as I do!Comfortable, fits well, warmJust what I was looking for
