I love these...I have two pairs, one yellow 11s the other white 10.5s. I was afraid when I bought them at the lack of padding...frankly I don't find it bother's me at all.
As others have said, the toe box is on the tight side, so I had to make a compromise. The 11s are a tad too long, toes have room to breathe but I get some movement. 10.5s have no movements north south but are a little tight east/west in the toe. You can't beat them in terms of price and weight. The Carbon sole is thin and light but super stiff.
The are very open so I do find myself wanting at least toe covers if the temps are below 60 F.
