Updates to Asics Gel 451
- The Asics Gel 451 is a lightweight running shoe that’s designed for the roads. It serves as a spiritual successor to the Gel Hyper Speed, the company’s premier series of racing flats. Its upper unit features a breathable mesh for long-term comfort and dryness, as well as a BOA® Fit System for a fast and secure adjustment.
- SpEVA is a cushioning piece that attenuates impact shock and gives energy to the foot of the wearer. It’s accompanied by the Gel® unit in the heel. These components work together to ensure a smooth and comfortable underfoot experience. Moreover, the vented underside heightens the intention of this shoe to be breathable.
- The forefoot section of the external pad makes use of DuraSponge, which is composed of a blown rubber compound. The high-wear areas feature the Asics High Abrasion Rubber or AHAR®.
Size and fit
The Asics Gel 451 is true to size. It accommodates the natural preferences of runners when it comes to length. The available width options are B – Medium for women and D – Medium for men. The semi-curved last and the form-fitting design of the upper traces the natural curve of the human foot.
The forefoot section of the Asics Gel 451’s outsole features the DuraSponge. This blown rubber unit offers traction and protection from abrasion, but it also adds a bit of cushioning through its malleable nature.
AHAR® or Asics High Abrasion Rubber is a material that shields the critical areas of the sole unit from wear and tear. Its capacity to provide grip is a facilitator of surface control.
Flex grooves allow the platform to move in conjunction with the foot. These shallow trenches help in bettering the toe-off phase of the gait cycle.
SpEVA is a cushioning material that runs the entire length of the Asics Gel 451. It’s a lightweight foam that disperses the impact energy generated by the foot-strike, then transfers that dynamic force to the foot and leg of the wearer. Such a process then invigorates the forefoot lift.
The Gel® Cushioning System is comprised of a silicon-based unit that’s placed in the heel section of the platform. Its purpose is to absorb the force created by landing the foot on the ground, thereby staving off any discomfort.
The Magic Sole is made up of a vented platform configuration. This design is meant to encourage breathability and moisture dispersion.
A Perforated Sock Liner adds a bit more cushioning for the underfoot. Its porous build further boosts the breathable purpose of this shoe.
Open Mesh is the Asics Gel 451’s primary upper unit. It is a lightweight and flexible material that looks like a multilayered net. Its ventilation holes allow environmental air to enter the foot-chamber.
A seamless construction permits the foot to experience a smooth coverage that’s free of irritating folds and lumps. The stitched reinforcements are restricted to the exterior frame.
The BOA® System is a fit-adjustment mechanism that involves stitched-on side panels, discrete fabric eyelets, stretchy cords, and a twisting knob. These elements work in tandem to provide a secure yet customizable fit. The wearer doesn’t even need to do any tying or looping; merely twisting the adjustable knob does all the work of the usual tie-and-secure lacing systems.
The padded tongue and collar are responsible for cushioning the top dimensions of the foot while also preventing in-shoe wobbling.
A pull tab is placed on the tip of the tongue unit. This fabric loop helps the runner in wearing and removing the Gel 451.
