Being a cat lover, I had a major obsession with the Charlotte Olympia kitty flats when they first came out! I was finally able to nab a pair from Bergdorf Goodman online (still available in select sizes here, and also in fuchsia here) for $282.50 when they went on sale.. which is 50% off original price of $565. They are unbelievably comfortable with no break-in period required. I would recommend to order the next half size up, so I ended up with a 37.
Then I came across these kitty flats by Zara. Unfortunately, they only come in girls sizes up to 5. They were too cute to pass up and were only $35.90. I bought the size 5 and I think they are an equivalent to a women's 7. They don't possess the same craftsmanship as Charlotte Olympia. They are a little stiff, and will probably require heel pads because they might blister my feet. I'll probably keep these and use them as a back up pair and not worry about dirtying them.
