As always, the core of any Mizuno shoe is the wave plate. This is a plastic plate that works like the suspension system in an automobile.
It gives the shoe rigidity, shock dispersion and a measure of torque resistance that other shoe designs struggle to equal. It also contributes to the characteristic firm ride that Mizuno shoes are known for.
The Wave Inspire 12 features a carryover wave plate from last year but the rest of the midsole is updated.
The Wave Inspire 12 continues with a traditional style upper as found on the 11. Almost all of the overlays are sewn versus being heat pressed as seen in the Wave Inspire 10.
The new upper is more substantial though and features more overlays than last year’s model did. A large Runbird logo connects the sewn eyelet row to a long overlay that encompasses both medial and lateral aspects of the shoe.
Additional heat pressed overlays shore up both sides as well. The toe box end cap is strikingly similar to the Wave Inspire 11 in both looks and in its sewn construction.
The mesh found in the upper now has an additional layer of fabric beneath it which makes for a thicker feel and causes the shoe to retain heat.
The tongue is medium thickness and the laces are the semi-flat style found on most modern running shoes. Interior fabrics feel identical to last season and are finely woven and nice to the touch. An OrthoLite style sockliner completes the package.
