Such good quality! The straps just arent quite tight enough to keep my feet in place, but theyre awesome other than that. Here we are in the month of July, and all 12 units I received have an expiration date of 10/2020. The rubber sole is thick enough to raise me above small puddles in bad weather, but thin enough for them to look a little dressy as well -- not so thick to be clunky & heavy. The romer G switches give amazing response times making each key stroke sensitive, precise, and satisfying. 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+. I have walked in my neighborhood for a week in it. I would not risk buying these again. I loved the lightweight and easy-hitch attach method this rack utilizes. Don?t be afraid to size down because It?s streches.
