These shoes are amazing! I am 15 years old and normally wear a 7-7.5 in women's shoes. I got size 37 and they fit perfectly. While is does take some effort to get them on, it is no more time than you would spend lacing up a pair of sneakers, and once you get in them, the time is totally worth it! When I wear my Vibrams, I feel like my toes and whole foot are aligned properly, which makes walking so much more comfortable! Once you break them in, they feel like a second skin, and you get the benefits of going barefoot without the ouches of rocks and thorns in your feet! I haven't worn them for any extremely long hikes/trips yet, but I'm sure they would hold up great based on what I've seen.
