Strength level: Mizuno WaveKnit S1
The outsole unit of the WaveKnit S1 is comprised of X10, a carbon rubber-based layer that protects the midsole from the abrasive nature of the asphalt. It has been touted as a highly durable compound that confidently staves off wear-and-tear while also doling out adherence over the ground.
Smooth and flexible ride
Deep flex grooves grace the forefoot section of the external pad of this daily trainer, as well as the transition rail of the lateral section. These trenches are designed to make the platform as flexible as possible, thus allowing the foot to move naturally through the gait cycle.
The decoupled heel isolates the impact shock of the foot-strike and smoothens the transitions through the gait cycle.
WaveKnit S1: Stable from lace-up down to the last stride
The midsole unit of the Mizuno WaveKnit S1 uses two layers of foam. The first one is the U4ic, a topsole that carries the foot and keeps it free from impact shock and movement deviation. It is flexible yet slightly firm, giving the foot a platform that isn’t wobbly or unwieldy.
The second foam that graces the midsole is the U4icX, a bottom layer that is responsible for receiving the brunt of the foot strike and the weight of the foot. This feature is fundamentally a softer version of the U4ic. A full-length implementation is applied to the WaveKnit S1, unlike some series like the Wave Rider and the Wave Inspire which implement a wedge version.
The Mizuno Wave is a thermoplastic piece that is sandwiched between the two primary cushioning technologies. This midfoot-to-heel accouterment is tasked with steadying the position of the foot, keeping it from buckling or accidentally shifting its stance.
Delivering a sock-like fit
The upper unit of the Mizuno WaveKnit S1 uses a knitted fabric, an element that exhibits a wrap that is similar to wearing a sock. The smooth configuration of the fibers prevents the skin from getting irritated.
It can't get more breathable than this
Breathing pores that widen as the material stretches and follows the shape of the foot are tasked with accommodating the flow of air into the interior compartment.
The sides of the façade have tightly woven portions to act as reinforcements and accents that boost the upright structure of the upper unit. They double as striped highlights that aim to make an impact on the visual aspect.
The Mizuno logo has been printed onto the sides of the silhouette as a determinant for brand recognition. These prints also double as overlays that help with the security of the foot.
The padded tongue and collar are made to cushion the upper portion of the foot, including the Achilles tendon, the ankles, and the instep. In-shoe wobbling and unintentional shoe removals are also incidences that are to be prevented by these parts of the façade.
