Die Verarbeitungsqualität ist absolut gut. I would definitely recommend buying these particular sandals from this specific seller(as I cannot vouch for any of the others). I added this one to the bottom and now I can do rows, hit chest and countless other exercises. These sandals look very similar to the Tory Burch and Sam Edelman ones, but are much more comfortable! Sturdy too - just when you stack them, theres nothing holding the racks together so you have to hold where they join, but not an issue (unless you forget and the racks have shoes on them). And to top it off, not returns on these. Then I filled the rails (not exceeding the weight limit and not using the extensions. I noticed some comments about the smell. Someone should come up with a real sandal again and they will make sales with social media ruling in world today. The spacing on the shelves is a good distance apart to hold larger items.
