Welche Sicherheitsklasse das allerdings erfüllt, vermag ich nicht zu sagen, laut Aussage meiner Versicherung zumindest sind Räder nur dann versichert, sofern sie mit einem Schloss der Sicherheitsstufe 10 gesichert sind. This product outperforms its pink counterpart in every way. They fit wide feet, are comfy, AND affordable. I will not purchase these again and cant recommend. Was sure which ever pair I chose I would be unhappy with (fit, look, sole, etc). I got a medium even though people said to size up just to make sure it was very snug and doing its job, the first day it was funny putting it on, but the next 2-3 days I went to the second row, today just for giggles I decided I’d try to put it on the tightest one or just try, and I did it. I have a hitch extender on my Jeep Wrangler for a bike rack to clear the rear spare tire. I was surprised at the quality of the packaging it came in. When I put the black pair on, you can see my toe sticking through . Vacumned the floor and today looked at the bottom the slippers.
