I sized down a full size, and I'm glad I did. My true to size boot (I ordered my true size as well as one size down) was WAY too big in the instep. I could lace the boot as tight as it goes and still have plenty of leather left to pinch at least an inch on the top of my foot. The toe box was definitely nice and roomy in my true to size boot, but it just looked way too big and felt too big. (I am not quite a wide width, but almost.) One size down is a hair too tight in the toe box, so I am hoping it stretches. The length is totally fine, but the toes are the one place that is tight. I'm hoping I can stretch the toe box a little over time. I rarely go smaller, but in this case, the true size boot was just overall way too big to look good.  ETA: (downgrading from 4 to 3 stars) Mine are definitely greenish black, not a true black. I'm disappointed. I have polished them with black shoe polish, and they still look green next to my black pants. Not cool for work when the goal was to wear black shoes with black pants. Also, after wearing them a few times, I'd say there is very little arch support and they're not super comfy. They need an insert, but since I sized down, I can't really fit one. I can't wear them for hours. They're just not that comfortable.
