I love these boots already. I have a narrow, petite foot, normally a size 6 in shoes, 5.5 in heels and I sprung for a size 8 to ensure I could wear these with a down bootsock inside and they fit perfectly. My foot doesn't even have room to slide inside the boot so do consider ordering A SIZE OR TWO UP for these. I was worried the 8 would be too big but a 7 would not have fit at all. The boots are great quality and they don't feel overly heavy to me. Planning on using them on an upcoming trip to Iceland and then again next Winter for outdoor activities. My feet usually get very cold so I'm hoping these do the trick. Will report back.
