Treads are still great, still good protection from the top. Not a deal breaker. Good value for money, come up slightly lsrge but there again they are slippers not street shoes. A few directions on how to hang pictures, but not how the hanger itself works. Promise of memory foam cushioning was the deciding factor. Awesome quality. Must have wireless charger stand device for Apple geeks! I purchased the Huawei Matebook (2016 model) for an ultra portable Windows machine primarily to do quick photo edits on the go, staying connected with email, business docs and social media, as well watching various media in HD+. It turned out that 2 of the 4 latch clios did NOT hold when tightened. for that kind of money, it is excellently made, and the sound is excellent.
