Bought these because what shoes actually stay on an infant's feet?  Saw others with booties that snapped closed and thought that's what these were.  What a nice surprise to find they're magnetized!  Super easy to get on & off, and very warm.  My daughter is 7.5 months, cruising around so I don't generally have her in them in the house, but on carpet and out & about they are life savers!  Not many socks stay on, and generally aren't warm enough anyway.  Highly recommend these cute booties!  Also, I bought the 0-6 month size and they still fit her at 7.5 months.  She's a pretty petite girl, but is long and lean, so I don't think her feet are abnormally small.  Enjoy!
