ill sometimes run my uppers (ilmoros) looser for more flexation in the park, but everything else, nice and snug.
and btw, helpful hint for eliminating toe bang:
Dr scholls pad cut up and fit around the outside of the toe box of your liner. lil duct tape to hold it in place (do it while your feet are in the liner tho so they arnt too tight). if you dont have enough room, you can taper down/remove footbed material from under your toes. works like a charm, even in snug boots. other option is silicone caulk.
just thought id throw that out there.
