Length of sandals are fine. I used two bungee straps as well with this rack, but Id have done that with a $200 rack. The buttons are very clicky and not in a good way like a mechanical keyboard. no more stickers and glue to my door, and they are made of aluminum. It happens in my house and it will in yours too. Ive had this installed in the concrete wall in my basement for 6 months now with no issues. Noise cancelling is on point. I don?t see myself standing in these all day as they really aren?t working clogs. I prefer full coverage on both areas. I wore them on excursions and hiking on Mexican cruise and I do not regret it at all!
