You are tall. I mean BIG. Seriously, I think that's where the name comes from because I ordered half a size smaller and SWIMMING in it. I sent them back and ordered a FULL size smaller and now they are comfortably loose. I also have moderately wide feet so I can probably get away with sizing issues. Don't waste time - order one size smaller. Regardless, they are amazing. No sweaty smelly feet - good quality shoes and I would like 6 more colors.
