Theyre the only shoes that I could was comfortably for my flat feet. They also fit the Hesh 2 Skullcandy headphones, as pictured in my review. These Birkenstock sandals are so cute! I am returning the product, and considering investing on more expensive model. The noise cancellation wasnt crucial for us but he says the it works pretty well when he does use it. At most I can fit three pairs of shoes in the side by side config and squeeze a pair of chucks stacked on top of each other on the end of each level. Both worked great until one broke in the first week. I was disappointed with the product. So plush and comfortable! These tiny things I plug in my ears have freed me up to go out at times I would not normally go out.
