I debated whether to order the large or medium but according to all the other ratings I went with the small/medium. My husband wears a 9 shoe with a wide width so the small/medium were probably a tad small. The small/medium fit when he received them and wore them about a week. At that point they started slipping off his feet like the ones that were too small. I washed them and they returned to the original size. I'm not sure the large/xlarge would have been better. Otherwise he loves these slippers. They were exactly what he wanted. Nice, warm weave, keeps his feet warm, easy to walk in until they slip off.My husband loves these. Keeps his feet nice and warm. I bought them for Christmas. The only complaint I have, is that they have begun to come apart at the seam. He only wears them at night, so I wish I could blame it on wear and tear but I can't. Hopefully the company will send a new pair because he really really likes them. We have wooden floors and it keeps him from sliding.Love them!Very good quality but kinda slippery and my toes press into the front tighter than I would like. Overall a good purchase, warm and good quality but I think next time I will try to find a different brandThe slipper socks fit just fine. My husband is enjoying the wear. They are keeping his feet nice and warm on these cold winter nights. They are made of good quality, very soft, and real comfortable. We will probably purchase a second pair to have on hand when the other pair is in the wash. I would highly recommend this purchase to male or female who is looking for a comfy sock to lounge around in.I enjoy the fit and the warmth.My reason for not rating 5 stars is that I don't feel there is enough non slip treads on bottom. The sticky dots I do not feel are sufficient.These are super warm, not slippery, and very comfortable. They are big and loose and I was afraid they'd just collapse around my ankles. They didn't.... they stay put in a surprising manner. I got the L/XL size and they fit my 13 W feet with room to spare.My Husband took a nap on the couch the other day and later he told me they were so warm that it kept all of him warm and he didn't even reach for a blanket. We've been married for 20 years and I've rarely seen him were socks and NEVER slippers. He's worn these every day since he got them.Good but sole wears out too fast even if only worn within apartment.Comfortable and warm. Fit as expected.I got these for my husband and he LOVES them!!!!!Took a chance on these and husband loves them.He likes them
