Coming from Sidi Mega, these shoes feel like they sit on a wider forefoot pedaling platform and have a good amount of forefoot room. I followed Lake's sizing guide for length/width and it seems accurate. They are light (size 45 535g) and the carbon soles feel very stiff/efficient. What I didn't like is that the toe cap area is stiffened/hard to keep its shape and at times bothers my big toe, versus the soft toe on the Sidi which conforms to your foot. Also, the single BOA can only be tightened while riding (you need to release the BOA if you want to loosen), and the traditional tongue doesn't feel like it is holding my foot snug even when the BOA is fully tightened, a dual BOA may work better or a more significant strap over the arch of the foot. Overall, it is good, but I would probably go for a shoe with a dual BOA closure OR with something that has a Shimano style "wrap around" upper if I were to buy again.
