Toebox is more accommodating than a lot of shoes but the midfoot is a little narrow. It's comparable to the Gel Res 8 in terms of a performer, more tank than sprinter. A decent shoe but between the Mizunos I found the Exceed 4 to be more comfy and fit a little better (wider midfoot) for my foot.
Both shoes are more than a year old so I’m doubtful any more vids will come out on them. I wanted to like the intense because it’s a good looking shoe but I really think the Exceed is better. Intense cushioning is a little hard for my taste (vs say a Gel Res which is more springy and cushioned). And probably why 98 percent of Mizuno’s pros are going with the Exceed. Although Bautista Agut wears a weird hybrid of the Intense sole with the Exceed upper.
