I wear a size 10 and ordered the 10, and it fits well. I walked pretty far in these the first two days and got no blisters. AT&T failed to inform me or their sales agent that all the flagship Samsung Galaxy 10 lineup do have a headphone jack port and the Samsung Galaxy Note 10 & 10+ do not. Ive since machine washed cold and air dried, theyre perfect. I loved the original Nike Free back in 2012 or so but they had changed the over the years so I had stopped buying them. A word of warning though, after reading this book, youll never be able to mindlessly double tap and swipe your way through your feed again, especially if you work for one of the countless brands getting conned or are raising kids in todays world. Charge it in for a few hours and its ready to go. Comes with the charging block and a cable as well which is nice. ), but for now its been great. Great product I use it daily to help reduce stress and I dont get easily upset, moody and irritable since I started taking this.
