Updates to Asics DynaFlyte 4

  • The Asics DynaFlyte 4 is fundamentally a product that is similar to its predecessor, the DynaFlyte 3, save for an upper that is configured to be extra secure and form-fitting. A cloth-like mesh replaces the cascading net that graced the previous version, presenting the runner with a wrap that is similar to an actual sock.
  • A flexible midsole foam offers reactive and well-attenuated steps. Hidden in the rear portion is a silicon-based GEL® piece that’s responsible for heightened impact attenuation. Also, a rubber base shields the contact points from abrasion and the debilitating effects of continued use.

Size and fit

The Asics DynaFlyte 4 is available in men’s and women’s versions, both of which follow the standard sizing scheme. Runners are welcome to get a pair in their usual sizes. However, being able to enjoy a pleasant in-shoe feel would benefit from personally testing the shoe first or getting ahold of user reviews from websites and other consumer feedback sections.

Influencing the fit are the various parts of the shoe that welcome the natural curvature of the human foot. These accouterments include the cloth-like quality and stretchy nature of the upper unit’s textiles, as well as the foot-shaped curve of the midsole lasting-board.

Outsole

The external pad of the Asics DynaFlyte 4 is made of AHAR® or Asics High Abrasion Rubber. This layer is designed to act as a barrier against the abrasive ground, thereby averting wear-and-tear. The durable make of AHAR® also allows it to last long.

The surface grip is also the responsibility of the outsole. Movement (like swerving, turning and braking) becomes effortless if there a helping of rubber at the base of the shoe. The DynaFlyte 4’s bottom layer has several non-prominent traction nodes to heighten the grip capacity.

Horizontal flex grooves line the forefoot section of this running shoe. These shallow channels are meant to make the platform more adherent to the bending capacity of the toe joints and tendons, bolstering the energized essence of the toe-off phase.

Midsole

FlyteFoam® Lyte is an Asics technology, and it is touted to be the lightest one yet. This feature aims to deliver a feeling of standing on a soft plane while also ensuring a springy ride. The full-length design welcomes the entire outline of the foot, supporting it at all times.

GEL® is a technology that uses a compound derived from silicone. This accouterment is placed in the heel section of the platform, stealthily adding more oomph to the underfoot experience. Furthermore, it has the ability to attenuate shock during the landing phase, thus making its inclusion a lucrative one for those who are used to the heel striking method. GEL® is used in many Asics series such as the Gel Cumulus and the Gel Kayano.

The Impact Guidance System (I.G.S.®) involves a rounded and decoupled heel platform, as well as a vertical groove which leads the foot through the gait cycle. Smooth heel-to-toe transitions govern such a feature.

A ComforDry™ sockliner is placed right above the primary cushioning system. This add-on is tasked with giving the foot with a soft surface on which to relax. It has moisture-managing capacities to prevent sweat from clinging inside the foot compartment.

Upper

The upper unit of the Asics DynaFlyte 4 is made of engineered mesh, a cloth-like material that has a structure similar to that of a sock. The soft and stretchy make of this feature has the goal of accommodating the natural shape and motion of the foot. Spaces between the fibers allow air to flow into, and through, the foot compartment.

Contrary to the DynaFlyte 3’s net-like exterior and incognito underlay system, version 4 places emphasis on the use of printed overlays. These synthetic prints serve as visual representations of the brand’s logo and stylistic choices. But they’re also crafted to help the lacing system when it comes to securing the foot in place and preventing in-shoe wobbling. A shiny finish makes these thin layers catch the eye.

The collar and tongue are padded. These parts of the upper are designed to cushion the topmost foot areas like the Achilles tendon, the ankles, and the bridge. Locking the foot at the center of the inner chamber is also a purpose of these elements.

A traditional lacing system graces the instep of the Asics DynaFlyte 4. Flat shoelaces snake through print-reinforced eyelets, covering a majority of the bridge of the foot. Adjusting the strands would tighten or loosen the fit, giving a customized in-shoe experience that follows the user’s preference.
