Louis Garneau Carbon HRS Shoe sizing, need help

I think I’m going to order a new pair of these LG Carbon HRS shoes but am not sure what size to get. I wear a size 12 in most shoes however the sizing chart says I should wear a 45.5 which is not an option. So i was wondering if these shoes tend to run large or small? Should I get a 45 or 46???

I have a pair of LG HRS road shoes in sz 46 that I can only use very thin socks. I wore a 46 in Sidi T2, 46 in Northwave and 47 in Sidi Genius 4. Running shoes are 13, but I like them a little big so I can keep my toenails. I think they run pretty true to length, just a little extra width and volume in the forefoot than Sidi.

my feet are half the size of yours! i wear an 8 1/2 in almost all of my shoes and own a pair of these in a 42 and they fit perfectly without socks. so in my size they run pretty true.

i definitely recommend them. they are super stiff and crazy comfortable after form fitting them.
