I wear a size 6 Nike flip flop, but a size 8. Not better or worse than any other on Amazon. Id go down a size if baby is in between sizes. I found them more comfortable than the similar sexi flips. I drove to the store but it had a long line of customers waiting outside so I ended up standing 40 mins in these sandals. You have Land?s End Moc Slippers! Son cómodos y prácticamente invisibles, te protegen el pié dando compresión en el arco del pie. The little carrying-case is handy, too. My shoes and boots are completely outnumbered and weve always had trouble organizing the multitudes of shoes in the house. No regrets, works well.
