I have had a few pairs of lakais, seems like they run pretty true, but kinda big when broken in, my carrol 5's and picos in 11.5 feel almost kinda big now that they have really stretched out, and thats the size I always wear in vans, sole tech, nike shoes. the lakais feel bigger, but not enough to really want to go a size down.
i'm pretty picky about the fit/feel for my skate shoes, most people say they need to go a half size up for DCs and for me 11.5 my regular size, is perfect. I have a narrow foot though, so I like a tighter secure fit. Feels like I wont roll my ankles so easily.
