-GO READ THE REVIEWS ON THE C693-
Get a half size larger than your normal boots, these run small. The laces are 62" (-ish) but run short. I managed to find a longer set and it makes it easier to put the boots on without having to unlace/relace every time. There's also no pull loop at the back, so there's nothing easy to grab when putting them on.
Much lighter than the 690/790 flight boots, and were great (besides being too small) for a day of paintball in the woods. I'll probably get a proper-sized pair, and second-hand the small set to a friend.
