I own four pairs of other 5.11 shoes. All size 11 reg. I have narrow feet and they all fit well. I have not hiked with these Cable Hikers but at first fit, I could have been ok with a half size to a full size smaller. The toe box is extra roomy. The heal is rigid and snug though. Not the same feel as my other 5.11 shoes/boots but looking forward to hitting a trail soon in these.
