They recommend sizing down on the boots, so I sized down on both the boots and officer shoes and got a good fit. I usually wear an 11-11.5 in dress shoes and boots and went with a 10.5 in each and it worked out great.
Make sure you follow their advice and size down -- I picked up a pair a couple weeks ago and went down from an 11.5 to 10.5. They're maybe the most comfy and well-fitting pair of boots I have, not to mention I've gotten boat loads of compliments about them.
I have a pair of brand new, unworn raw selvage 14.5oz SK's up on Grailed - but also interested in trading for some size 32's (with preferably less than 1 week of wear, though ideally also new). May also be interested in other RGT stuff - let me hear offers if you have them.
