Mine arrived today and I tried them on in the house, and here are my first impressions:
I can confidently say that the fit is definitely more robust and less narrow than the Wave Exceed 3's, which I had to immediately return because of the narrow fit.
I would say I'm on the wider side of D, but not enough to consider myself in the wide foot category.
I have been wearing the 2018 Barricades for the last 8-9 months, which I've gotten very much used to, but I use a runner's loop to secure a tighter fit around the ankles. My favorite tennis shoes were the Court FF 1's which I unfortunately never stocked up on, and I'm a big fan of the sock fit construction.
Compared to the Barricades, I did not have any noticeable difficulty fitting into the Wave Exceed Tour 4, although it does feel slightly tighter trying to put them on. I would say, if the shoe were even a little bit tighter than its current form, I would return them, but they are just wide enough to provide a comfortable fit. Toe box was comfortable.
Immediately when you pick up the shoe, you can notice how light they feel. They are very light! I cannot believe these come with a 6 month warranty. Has Mizuno cracked the code on light weight, efficient performance and durability? I'm not sure. Side by side, the treads and sturdiness of the Barricades makes it feel like a tank compared to the Wave Exceed 4's.
But when I look at the "depth" of the treads, I can see that they are not much different than the Barricades from inside, and I am not particularly hard on my shoes, nor do I slide.
So far, this looks like a great shoe to me. I can still feel connected to the ground, although not as connected as the barricades. But this is okay with me.
Unfortunately, I will have to wait until the weekend to see how these shoes hold up on the court. It should be interesting, but very good first impressions for me. I wear size 10.5, and the Wave Exceed Tour 4 at size 10.5 felt just right. I also have high arches, and it seemed like I could use a little bit more arch support, but we will see. I'm not sure if there will be any room for insoles if it's going to make the fit tighter.
