- Mizuno deals the Inspire 11 with several major modifications to completely erase memories of the past version’s noticeable failures. First up is the revamped upper, which is now a remake of the past versions where stitched overlays are a major theme. This is to address issues of a loose upper that created all sorts of problems for the runner. The new version gives a nice hug that keeps the foot secure from start to finish.
- Another major change is the material use in the Wave Plate. Mizuno goes back to the one used in earlier models as the one used in the prior version lacked the trademark shock dispersal and pop in the heel. Mizuno fans will recognize the performance of the Wave Plate in 11th Inspire.
- To compensate for the firmness of the old thermoplastic material and design of the Wave Plate, Mizuno made the forefoot more curved or springy while the last is a little curved as well. This helps with the flexibility and the transition from the heel to the forefoot. The Ortholite sockliner is also made of softer material to reduce the firmness of the ride.
The significant makeover also involves the fit. The Mizuno Inspire 11 has a snugger fit in the heel to the forefoot. With the new last and improved upper, there is an enhanced lockdown feel in the heel, the midfoot, and the forefoot. Despite the curvier last, there is still decent space in the toe room for a natural splay of the toes. Medium to extra wide are the available widths of the shoe while the shoe length is standard.
The outsole is made mostly of blown rubber bar the heel where the more durable X10 carbon rubber serves as a deterrent to wear and tear. This outsole material is used in some Mizuno shoes for running such as the Inspire 15, Rider 22, and Creation 20.
Flexibility is provided by flex grooves with a segmented crash pad that helps with shock attenuation.
The thermoplastic plate known as the Wave Plate occupies the heel and the forefoot sections of the Wave Inspire 11. From the heel, it extends to the midfoot to deliver torsional rigidity and arch support. Mainly, the technology helps with shock dispersal and transition through the gait cycle. Handling the main cushioning duties falls is the U4iC midsole foam. While it is a bit firm, it is lighter than the AP+ with just about the same durability. The SR Touch foam in the heel softens the impact in the heel.
A very breathable mesh covers a large portion of the upper. As mentioned, there are several stitched overlays, including the Runbird logo that delivers the vastly improved fit of the upper. The tongue and collar are sufficiently padded while a plush Ortholite Sockliner helps soften the landing and enhance fit.
