Comfort and Fit of the Mizuno Wave Rebellion Pro
Silke: The upper is an engineered mesh with 90% recycled material, it is very thin and breathable. There are printed Mizuno overlays and thin internal reinforcements to lock your foot securely. The very thin tong is not gusseted, but the laces are fixed so there is no sliding at all. The very thin laces seem a bit short (and the insoles/ sockliner is glued.
There is not a lot of padding around the ankle, but enough to make it feel comfortable. The heel is slightly padded and there is a stiff part just in the back to give structure and to keep your heel locked. I found that my foot felt very secure at any pace.
Sadly this shoe runs a bit short. If you have the possibility you should try it on your feet otherwise go half up. I have to wear my thinnest socks to make it fit, but then it offers a perfect snug race fit.
Ivan: When first putting on the shoe, the fit was extremely snug and especially the toe box felt cramped. I was convinced that I would need to go half size up to fit the shoe without getting blisters around my toes. However, having used the Rebellion Pro with thin socks, I am not that convinced anymore. At least I haven’t gotten any blisters from the quite pointy toe box and I got just enough space for a fairly comfortable “race” fit. Helped along by a super light and breathable upper.
However, I do have one serious issue and that is the heel collar. Despite being soft and pliable, it bruises my achilles. It might have to do with the overall snug fit, putting some pressure in the back. Not being able to use thicker socks leave my achilles even more exposed and I need to use band aid or sports tape to avoid a bloody achilles during longer runs.
Overall, I find the upper snug, but actually pleasant apart from the achilles rubbing. It is simple, thin and breathable but the lockdown is good. All that is missing is a tiny bit more volume and perhaps some additional padding around the heel cup and the tongue.
