I bought these last year and wore them a few times. They are very light and warm, and the band keeps them from slipping off. However, the size doesn't fit me, so I haven't worn them this year. I'm not sure if it's because of the size issue, but there is a tear in the silver film on the inside of the right foot, around the ankle (see image 8). The down fabric underneath is not torn, so they can still be worn warmly. There are no problems with use, but the non-slip dots on the underside show signs of wear. Please understand the above points before purchasing. MIZUNO Room Shoes Boot Type 25-27cm Black - Filled with padding - Washable - Convenient to carry - Water repellent - Brand: Mizuno
