My grandson has a pair of slides which are made by adidas, but thes are much better for his little sister Since we added these, they fit so much better with less slipping. I ended up returning these, because everyone suggested ordering up a size -- that resulted in them being huge.

I bought these for frequently used spices to put next to the stove. Got that taken care of, only to find out I cannot use it for its intended purpose.
